Why Notion is Not Syncing: Common Causes
Before jumping into fixes, understanding the root cause saves time. Notion syncing failures typically result from:
- Unstable Internet Connection: Notion requires active internet to sync. Weak Wi-Fi or mobile data causes sync failures
- Outdated App Version: Old Notion versions contain sync bugs fixed in newer updates
- Corrupted App Cache: Accumulated cache data interferes with sync processes
- Background App Restrictions: Android and iOS battery savers block background syncing
- Notion Server Issues: Occasional server outages affect all users simultaneously
- Incorrect Date & Time Settings: Wrong device time causes authentication failures
- Full Device Storage: Notion cannot cache data when storage is critically low
Check Notion Server Status First
Before troubleshooting your device, verify Notion’s servers are operational.
Visit notion.so/status to check real-time server status. If Notion shows an outage or degraded performance, wait for their team to resolve the issue — no device-side fix will help during server problems.
Notion typically resolves server issues within 1-2 hours. Follow their official Twitter/X account @NotionHQ for real-time updates.
How to Fix Notion Not Syncing on Android
Solution 1: Check Your Internet Connection
Notion requires a stable internet connection to sync changes across devices.
How to Check:
- Open any website or YouTube video to verify internet is working
- Switch from Wi-Fi to mobile data (or vice versa) to identify connection issues
- Restart your router if Wi-Fi seems slow or unstable
- Move closer to your Wi-Fi router for stronger signal
Pro Tip: Notion syncs best on Wi-Fi. If mobile data is slow, enable Wi-Fi calling and switch to a faster network before editing important notes.
Solution 2: Force Close and Reopen Notion
Sometimes Notion gets stuck in a broken sync state. Force closing resets the connection.
How to Force Close on Android:
- Tap the Recent Apps button (square icon)
- Find Notion in recent apps
- Swipe it away to close completely
- Wait 10 seconds
- Reopen Notion and check if syncing resumes
This simple fix resolves sync issues in approximately 40% of cases according to user reports.
Solution 3: Clear Notion Cache on Android
Corrupted cache files are the most common cause of Notion sync failures on Android.
How to Clear Notion Cache:
- Open Settings on your Android device
- Tap Apps or App Management
- Find and tap Notion
- Select Storage or Storage & Cache
- Tap Clear Cache
- Reopen Notion and test syncing
Important: Clearing cache does NOT delete your Notion data. All pages, databases, and notes remain safely stored on Notion’s servers.
This solution fixes syncing in approximately 60-70% of Android cases.
Solution 4: Disable Battery Saver for Notion
Android’s battery optimization aggressively restricts background app activity — including Notion’s sync processes.
How to Disable Battery Optimization for Notion:
- Open Settings
- Go to Battery or Battery & Device Care
- Tap Battery Optimization or App Power Management
- Find Notion in the list
- Select Don’t Optimize or Unrestricted
- Restart Notion
On Samsung devices, also check: Settings > Apps > Notion > Battery > Allow Background Activity.

Solution 5: Update Notion to Latest Version
Outdated Notion versions frequently cause sync failures as servers drop support for older builds.
How to Update Notion on Android:
- Open Google Play Store
- Tap your Profile icon (top right)
- Select Manage Apps & Device
- Find Notion and tap Update
Each update includes bug fixes targeting sync reliability. Always keep Notion updated for best performance.

How to Reinstall:
- Long press the Notion icon
- Tap Uninstall and confirm
- Restart your Android device

- Log back in with your account credentials
Note: Reinstalling does NOT delete your Notion workspace. All data is stored on Notion’s cloud servers and fully accessible after logging back in.
How to Fix Notion Not Syncing on iPhone

Frequently Asked Questions (FAQs)
Why is Notion not syncing even with good internet?
If internet is working but Notion still won’t sync, the issue is likely corrupted cache data, battery optimization blocking background sync, or a temporary Notion server issue. Clear the app cache on Android (Settings > Apps > Notion > Storage > Clear Cache), disable battery optimization for Notion, and check notion.so/status for server issues. If all three check out fine, sign out and back into your account to refresh authentication.
Does clearing Notion cache delete my data?
No. Clearing Notion cache is completely safe and does not delete any of your notes, pages, databases, or workspace content. Cache only contains temporary files stored locally on your device to speed up loading. All actual Notion data is stored on Notion’s cloud servers. After clearing cache, simply reopen Notion and your content will reload automatically.
How long does Notion take to sync?
Notion typically syncs changes within 5-30 seconds on a stable internet connection. Large databases with many images may take 1-2 minutes to fully sync. If syncing takes longer than 5 minutes, there is likely a connection issue or server problem. Check your internet connection and Notion’s server status page.
Why does Notion sync on laptop but not on phone?
This indicates a device-specific issue rather than an account problem. Common causes include battery optimization blocking Notion’s background sync on mobile, insufficient phone storage preventing cache storage, or an outdated Notion app version on your phone. Update Notion on your phone, disable battery optimization, and clear the app cache to resolve phone-specific sync failures.
Can I use Notion offline on Android and iPhone?
Yes. Notion has an offline mode that lets you view and edit previously loaded pages without internet. Changes made offline sync automatically when you reconnect to the internet. However, offline mode must be enabled manually in Notion Settings, and only pages you’ve previously opened are available offline. New pages created offline sync once internet connection is restored.
Is Notion syncing free?
Yes. Notion’s syncing feature is included in all plans including the free tier. All changes sync automatically across unlimited devices at no additional cost. Notion’s free plan includes unlimited pages, blocks, and synced devices for personal use. Team and Business plans add collaborative features but syncing itself is always free.
Conclusion: Get Notion Syncing Again
Notion sync issues are frustrating but almost always fixable with the right approach. The seven solutions above — from checking internet connection to reinstalling the app — resolve 95% of syncing problems on both Android and iPhone.
