### Steps to reproduce

Take1)

1. Take Android 11 (Samsung A40)
2. Create some photoes
3. Create some screenshots
4. install the APK provided here [https://cloud.nextcloud.com/s/CBsW4ST38LQ8gCP] ( https://github.com/nextcloud/android/issues/16550 )
5. accept akku not-optimized and full access for the client
6. Activate sync of the two default provided folders (Camera and Screenshots).
7. The folders did not exist on the server yet (i was used to they just get created).
8. disable wifi only.
9. enable existing files
10. enable use subfolders yyyy/mm
11. eneable "new version renaming"

Take2)

1. disable the default synch (screenshots and camera)
2. create custom synch orders
3. one for Camera one for Screenshots
4. create both target folders on nextcloud manually
5. all other settings as above
6. start sync
7.

### Expected behaviour

the existing files get synched. New taken pictues are synched.

### Actual behaviour

take 1) Nothing was synched at all. Not even the folders created. (logs_0.txt)
take 2) Only new pictures get synched. Existing ignored (logs_1.txt / logs_1b.txt). Log 1b is after the sync happened. i thought it would not happen anymore. but actually it came a bit later.
