Sync Not Working for Certain File Types After Update?

Some files sync.

Others don’t.

Nothing else changed.

This is not random.

Same app.

Same account.

Only certain file types fail.

This isn’t a full sync issue.

It’s a format-specific failure.

The App Works — But Not for Every File Type

Your sync is partially working.

  • common formats → sync normally
  • specific formats → fail repeatedly

The difference is the file type.

Same Data. Same Account. Only Certain Files Break

This is the key pattern.

  • some files always succeed
  • others never complete

Nothing else changed.

So the issue is not:

  • your account
  • your connection
  • the entire app

It’s how specific formats are handled.

What Actually Fails

The app cannot process certain file types correctly.

  • unsupported or newly restricted formats
  • encoding or structure mismatch
  • format validation failure

The request gets rejected or never completes.

So sync appears stuck.

Why It Happens After an Update

Updates often change file handling rules.

  • new format restrictions
  • stricter validation logic
  • different parsing behavior

Files that worked before may now fail.

Why There’s No Error

Because the failure is silent.

  • no clear error message
  • no failure alert
  • just no sync completion

So it looks like sync is working — but specific files are ignored.

How to Confirm This

  • some file types sync normally
  • specific formats always fail
  • retrying gives the same result

If only certain file types fail, format is the trigger.

What Actually Fixes It

Change how the file is handled.

  • convert the file to a different format
  • re-export or recreate the file
  • simplify structure before syncing

Keep the same file type, and sync won’t complete.

What You Should NOT Do

Do not reinstall the app.

Do not reset your account.

Because:

  • your sync system is working
  • only specific formats are failing

The issue is format-specific.

Final Answer

Your sync didn’t break.

Certain file types are no longer being processed correctly.

So when only specific formats fail after an update,

change the format.

That’s the fix.
