Hello!
With my Galaxy S21, I can’t even “see” .csv and .pdf files that exist in the download folder when I try to select them for uploading. JPG and MP4 work fine, and in the Nextcloud app settings, I can’t find any filters. In the Android app settings, I can’t find any authorization options for files (only for “Photos and Videos”).
When I select my PDF files through the native file explorer and send them via the NC app, they don’t send immediately – an error appears, and they stay in the queue. When I tap on them again, they are sent. That’s really frustrating – any ideas?

Select them how/where? Manually? Via Auto-upload? etc.
If using Auto-Upload, are you using Custom Folders? The default auto detected folders are only for media.

Depends - what’s the error you’re seeing? 
Select from the manual upload function. Auto upload never worked with Galaxies…
