Logs

If applicable, you can post the iOS app or server logs (removing any sensitive information).

Reasoning or why should it be changed/implemented?

Offline mode is important for integration in other apps and especially on iPads (e.g. when working on train) highly appreciated

Environment data

iOS version: 18.1

Nextcloud iOS app version: 6.1.6.1 (Testflight) --> but AFAIR the bug has already been present in <6.1.4
--> it's not reproducible in 6.1.5 since the files integration there is broken completely as mentioned in #3180

Server operating system:

Web server: nginx

Database: MySQL

PHP version: 8.2

Nextcloud version: 29.0.7
