Sync Not Working on Android After Update — Android Is Blocking Background Sync
Sync works on iPhone.
Works on desktop.
Works on web.
But not on Android.
Same account.
Same setup.
Different behavior.
Android Is Blocking Background Sync
The update didn’t just install.
Android is blocking background sync after the update.
- background processes are restricted
- battery optimization is re-enabled
- sync pauses when the app is not active
The app is installed — but not actively syncing.
Why It Only Happens on Android
Android behavior varies by device.
Especially after updates.
- some devices aggressively stop background apps
- system optimization overrides app behavior
- manufacturer settings silently block sync
Sync doesn’t fail — it gets blocked.
What It Looks Like
- sync works on other platforms
- Android shows outdated or no data
- sync runs only when the app is open
No error. Just no background sync.
How to Confirm It
- keep the app open and observe sync behavior
- close the app and check if sync stops
- compare with another device
If it only works while open, background sync is blocked.
What Actually Fixes It
You need to remove Android restrictions.
- disable battery optimization for the app
- allow background activity
- restart the device
Also check:
- data saver is off
- the app has full network access
Until you remove the restrictions, sync won’t return.
Final Answer
Your sync didn’t fail.
Android is blocking the app from syncing in the background.
So when it works everywhere except Android,
don’t check the server.
remove the restrictions — and sync will return.
