Sync while a form is open causes the form to close, loose data entered up to that point

Nobody has claimed this yet.

**Description**

After having received this report from others since a few months now, I finally seen this myself in person.

It seems to exist a specific timing that when sync is running and the form is open, it causes the form to close and the feature to be deleted.

I had auto-sync off, but started sync manually (a "long" one as it was transferring many photos), then digitized a feature and while the form was open I could see for an instant a message that the feature was deleted, and of course the form closed and the entered data was lost.

The reports I received previosuly about this were from people with auto-sync on, and I guess that the fact that it now runs every minute it causes this problem to be more frequent, see also https://github.com/MerginMaps/mobile/issues/4178 (so there seems also the be the issue that auto-sync should not run when digitizing/editing a feature, but it does not seems to be the case).

App version 2026.2.0

Start by reproducing a sync while a feature form is open, using the manual or automatic sync scenarios described in the issue. Trace the sync and digitizing/editing paths to identify why the feature is deleted; done means syncing no longer closes the form or loses entered data.
