best way to troubleshoot is reading adb logcat while interacting and seeing what it stumbles into. As edrive syncs bidirectional (cloud deletions sync back, no file versioning), there’s danger of mishandling and a backup on a third device is sensible.
I saw 3 reports on this the last few months similar to yours
- Broken sync between my phone & ecloud.global?
- Synchronisierung (german language thread)
- Feedback for v1.8 - #94 by Ture
As of now, I don’t see something that reads exactly like this issue - Issues · e / Backlog · GitLab
while you could debug this, you can also disable the file sync and use nextcloud client to sync to murena, it has a larger user base and thus sees more scrutiny
