Steps to reproduce

Steps to reproduce:

• Open file/image in e.g. gallery app
• check the file name
• click "share to" button
• select Nextcloud app
• check upload file name

Expected behaviour

File name should remain unaltered and original file name must be preserved. The issue occurs since app was updated yesterday, Previous version of the app allowed upload with original file name.

Actual behaviour

original file name was e.g. IMG_20260724_095541.jpg (date/time based format). In the upload dialog Nextcloud App suggest file name such as 1784890751676.jpg (looks like timestamp format).
