⚠️ Before posting ⚠️

• This is a bug, not a question or an enhancement.
• I've searched for similar issues and didn't find a duplicate.
• I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. Select a picture from the gallery on a Samsung S21
2. Chose to share/send the picture, chose "nextcloud" for that
3. Navigate the folder structure on the server side inside the Android app.
   Those network requests are logged on the server side.
4. Once you see the folder on the server side inside your android app chose the "Upload" button.
5. A popup appears for maybe 1/10th of a second and vanishes again, nothing else happens.
   The picture is not uploaded, no request for the upload is logged on the server side.
6. That can be reproduced in 100% of all attempts.

Expected behaviour

The picture should get uploaded to the server.

Actual behaviour

The picture is not uploaded, no network request is done for the upload, although other network requests to the nextcloud server are done and succeed.

Server error logs

No logs are recorded for the expected upload request.

Additional information

This is a client only issue. I observe no issues uploading from other devices.

The discrepancy: the app does indeed have a network connection, everything works, it can browse the server side folder structure, it can create folders on the server side.
Only when then trying to upload a file then above error suddenly occurs which does not make much sense.

This is not my device, if required I can perform additional tests, but that requires a bit of time to get hold of the device again.
