Sync Not Working After Update Until Cache Is Cleared?

The app looks normal.

But data won’t update.

You refresh.

Nothing changes.

Then you clear cache —

everything updates instantly.

This is not a sync failure.

This is a cache conflict.

Cache vs Real Data

There are two layers:

After the update, they don’t match.

The app keeps showing old cached data.

So it looks like sync failed.

But it didn’t.

The update changes how data is stored.

So outdated data stays visible.

Because it removes the old layer.

Now what you see matches reality.

If clearing cache fixes it, cache was the problem.

Reset the cache layer.

Keep the old cache, and data won’t update.

Do not reinstall immediately.

Do not assume sync is broken.

Because:

The issue is cache — not sync.

Your sync didn’t fail.

Your app showed outdated cached data.

So when nothing updates until you clear cache,

reset the cache.

That’s the only fix.
