### Steps to reproduce

F-Droid Nextcloud app 3.31.4
Android 15 / Pixel 8a
Full permissions to everything

The app ignores randomly some files and does not upload them. I'm only syncing my camera folder and sometimes a whole day is not uploaded, sometimes just a bunch of photos shot in close proximity and sometimes just 1 or 2 of a set are not uploaded.

### Expected behaviour

Why is that happening? What can I do, apart fromanually uploading?

### Actual behaviour

Files are missing

### Android version

15

### Device brand and model

pixel 8a

### Stock or custom OS?

Stock

### Nextcloud android app version

3.31.4

### Nextcloud server version

30.0.6

### Using a reverse proxy?

I don't know

### Android logs

_No response_

### Server error logs

```bash

```

### Additional information

Some improvement ideas:
The app should e.g. once a day check for missing file and upload them?
The app should have force upload of missing images so I can at least fix it kinda myself?
