Steps to reproduce

1. Open NextCloud app
2. Go to Settings > Advanced > Change filename mask
3. Enable "Maintain original filename"
4. On a different phone, take multiple photos
5. Airdrop the new photos to the phone that contains the NextCloud app
6. Wait for NextCloud auto upload to kick in
7. Auto upload fails with "423: WebDAV Locked: Trying to access locked resource"

I believe this error occurs because multiple different photos are somehow named "FullSizeRender.jpg", which causes a conflict when uploading the photos. Photos can be lost because they aren't uploaded to NextCloud and might be manually removed from the photo gallery

Expected behaviourTell us what should happen

Somehow airdrop photos are labelled as "FullSizeRender.jpg".
The expected behaviour should be that the new unique photos will either have it's original filename (IMG_0001.jpg), or in case of a name conflict, a new filename will be selected (IMG_0001_1.jpg).

Actual behaviour

Unique photos with the name "FullSizeRender" are not uploaded to the NextCloud server. This happens with any extension (.mov, .jpg, .heic, etc)

Logs

N/A

Reasoning or why should it be changed/implemented?

Because the user doesn't know which photos aren't uploaded, they might permanently delete a photo from their library, thinking that it was saved in their Nextcloud server.

@marinofaggiana Thinking that my photos were successfully saved to my Nextcloud server, I've permanently lost around 300 photos because of this bug 😞 I'm not too sure if this is a new bug, or an existing one. If there's anything I can do to help, let me know 😊
