Offline Files opening-procedure very slow due to check for newer versions

### Is your feature request related to a problem? Please describe.
I often use NextCloud to store/share/access files for travelling documents
A very common issue for me is as i want to open up my boarding pass right getting into the plane when its getting hectic
- I already synced the full folder to my android phoe
- I already created a shortcut on launcher to directly open boarding pass
- After opening the file, there comes a very very long loading screen with the message "trying to find newer file" (or something)
- During this very very long phase, the document can not be seen (and in my case, the QR-code can not be accessed)

### Describe the solution you'd like
- As i open up a file, it immediately opens/shows the current version on the phone
- A loading icon/dialog could be shown in a corner or something and check for newer versions more passively/in the background
- During the "open-phase" where the app tries to contact the NC-server, the files are directly available/zoomable/clickable in the latest version on the phone

### Describe alternatives you've considered
- There are no alternatives, because im syncing my files offline to have them available immediately

### Additional context
- none
