When Notion's mobile app fails to sync properly, the issue typically stems from connectivity problems, corrupted local data, or session conflicts between devices. Most syncing problems can be resolved through systematic troubleshooting steps that refresh the app's connection to Notion's servers. The solutions range from basic connectivity checks to complete app resets, with the most effective methods involving logging out and back in, clearing cached data, or reinstalling the app entirely.

Key findings from reliable sources include:

• Logging out and back in resolves sync issues for many users by refreshing the account session ^[1][3]
• Clearing app data or cache fixes corrupted local files that may block synchronization ^[2][3][6]
• Reinstalling the app serves as a nuclear option that preserves cloud data while eliminating local corruption ^[4]
• Network stability is foundational—syncing requires consistent internet access, and switching networks can help ^[3][9]

Troubleshooting Notion Mobile App Sync Issues

Basic Connectivity and Session Refresh

Syncing failures often begin with unstable connections or stale sessions. Before attempting complex fixes, verify your internet connection and refresh Notion's session state. Mobile devices frequently switch between Wi-Fi and cellular data, which can disrupt sync processes if the handoff isn't smooth.

• Check and reset your internet connection:
• Ensure you're connected to a stable network (Wi-Fi or 4G/5G) ^[3]
• Restart your router or switch to a different network if syncing stalls ^[3]
• Disable VPNs or firewalls that might block Notion's servers temporarily ^[9]
• Log out and log back into your account:
• This forces Notion to re-establish a connection with its servers ^[1]
• On mobile: Tap your profile icon → "Log out" → Re-enter credentials ^[3]
• Repeat this on all devices to ensure session consistency ^[1]
• Restart your mobile device:
• A simple reboot clears temporary system glitches affecting apps ^[5]
• This is particularly effective if Notion appears frozen or unresponsive

These steps resolve the majority of transient sync issues by eliminating network instability and session conflicts. If problems persist after these checks, the issue likely involves corrupted local data requiring deeper intervention.

Advanced Data and App Reset Procedures

When basic refreshes fail, corrupted cached data or app files are often the culprit. Mobile apps accumulate temporary files that can conflict with sync processes, especially after updates or prolonged use. The solutions here involve clearing this data or completely resetting the app while preserving your cloud-stored content.

• Clear the app cache (Android) or offload app (iOS):
• On Android: Settings → Apps → Notion → Storage → "Clear Cache" ^[3]
• On iOS: Settings → General → iPhone Storage → Notion → "Offload App" (keeps documents but removes app data) ^[6]
• Note: Clearing cache won't delete your Notion data, but offline content may require re-downloading ^[3]
• Reset the app completely via reinstallation:
• Delete the Notion app from your device ^[4]
• Reinstall from the App Store or Google Play Store
• Log in again—all data syncs from Notion's servers automatically ^[4]
• This is the most thorough fix for persistent corruption issues
• Use Notion's "Copy and sync" feature for stubborn pages:
• Open the problematic page on desktop/web
• Click the three-dot menu → "Copy and sync" to force a server-side refresh ^[6]
• This can resolve cases where specific pages refuse to sync
• Check for workspace complexity issues:
• Large databases or heavily nested pages may sync slowly ^[9]
• Try syncing smaller sections first to isolate problematic content

For users experiencing sync issues across multiple devices, performing these resets on all affected devices ensures consistency. The reinstallation method is particularly effective because it guarantees a clean slate while relying on Notion's cloud backup to restore your workspace.
