### Bug description

Hello seems google file permissions are showing their ugly head again. I have the latest release of Android 16 on my google pixel 9 xl and the Nextcould App automatic sending is malfunctioning. App reports a successful send but the message under the file (pictures&videos) says Could not find local file. Upon checking on the server itself the files are missing

### Steps to reproduce

1. Use Google Pixel 9 XL with Android 16 BP2A.250605.031.A2
2. Download any picture/video to your phone
3. Make sure the image is in the folder setup for automatic sending (options dont seem to matter)
4. Go to Uploaded section, you will see images are correctly detected and appear to say they have been uploaded, but the message under each one states : "Cant find local file"
5. Go to the correct folder and see that files are actually there
6. You can manually upload the files without issue
This seems to point to a read/access issue for the automatic upload

### Expected behavior

Instant upload should transfer the files to server.
