Sync Completed After Update — Why Some Data Disappeared Right After Installing the New Version
You updated the app.
It installed fine.
No errors.
Sync completed.
But something changed.
Some files are missing.
Some folders look empty.
Not everything — just parts.
This is not a sync failure.
The update changed how your data is rebuilt and displayed.
An Update Resets How Data Is Loaded
After an update, the app does not continue from the same state.
It rebuilds its data structure.
- new loading rules apply
- cache is cleared or replaced
- data indexing starts again
That means what you see right after opening
is not the full dataset yet.
Why Only Some Data Is Missing
The app loads data in priority order.
- recent files first
- active folders next
- older or large data later
So after an update,
you are only seeing what loaded first.
The rest is still there — just not visible yet.
Three Real Causes After Update
If data disappears right after updating, it usually comes from one of these:
- cache was reset and not fully rebuilt
- indexing is still rebuilding in the background
- default view changed after update
Your data was not removed.
The app is rebuilding access to it.
Case 1 — Cache Reset
Updates often clear cached data.
Without cache:
- only limited data appears first
- older items seem missing
Typical pattern:
- data appears after refresh
- data returns after reopening
This usually stabilizes within seconds to a few minutes.
Case 2 — Reindexing in Progress
After updating, the app rebuilds its internal index.
This affects:
- search results
- file listing order
- folder visibility
Until indexing completes,
some data may not appear at all.
This can take minutes depending on data size.
Case 3 — Default View Changed
Updates sometimes reset the default view.
- recent tab opens first
- filters may be applied automatically
- specific categories may be hidden
This creates the illusion of missing data.
You are seeing a limited scope.
How to Identify What’s Happening
- data appears after refresh → cache rebuild
- search cannot find items → indexing in progress
- only certain sections missing → view limitation
The behavior reveals the cause.
What Actually Fixes It
Do not panic or resync immediately.
Fix the current state first.
- refresh or reopen the app
- navigate through folders and sections
- wait for indexing to complete
If needed:
- log out and log back in
- check network stability
If data is still missing after several minutes,
then check account or sync scope.
Final Answer
Your data did not disappear after the update.
The app reset how it loads and displays your data.
So when some data looks missing after updating,
you are seeing an incomplete rebuild — not data loss.
