Description

Steps to reproduce
  1. Create an end-to-end encrypted (e2e) folder (e.g. Desktop App)
  2. Load data into the newly created folder
  3. Mark the new folder with data in the Nextcloud iOS APP as "available offline".
  4. Deactivate mobile radio and WLAN on the iPhone.
Expected behaviour

I was expected to be able to access the E2E data offline. It is possible, but only the cryptic file names are displayed. As soon as mobile/WLAN is enabled again, the correct file names are displayed again.

Actual behaviour

only cryptic file names are displayed

Logs
Reasoning or why should it be changed/implemented?

With the cryptic file names the desired file/folder cannot be found.

Research direction

Begin by reproducing the issue in the Nextcloud iOS app using an end-to-end encrypted folder marked available offline, then inspect the offline E2E file and folder-name handling. Done means encrypted content retains the correct readable names with mobile data and Wi-Fi disabled, while online behavior remains unchanged.
