Sync Not Working After Reinstall on Outdated System Version?

The app installs fine.

But sync never starts.

Even though everything looks normal.

It can feel like your device just won’t work with the app.

But the issue isn’t the app itself.

What’s Actually Happening

Your device is running an older system version.

The app expects a newer system than your device has.

So sync cannot run properly.

Sync depends on system-level features.

Some system features the app needs are missing or outdated.

So the process never starts or never completes.

Reinstall gives you the latest app version.

But your system version stays the same.

This creates a mismatch.

It looks like a sync problem.

But it’s a compatibility issue.

Update your system version.

This aligns the app with your system.

Your device may no longer be supported.

In that case, sync may not work reliably.

Your sync didn’t fail.

Your system is too outdated for the app.

Updating the OS resolves the issue.
