open texteditor runs in failure after some time

Expected behaviour

Access is established again or texteditor is closed. Way to main menu is not clear.

Actual behaviour

App is blocked, can change some details but can't close the editor itself.

Steps to reproduce

1. open file in texteditor
2. copy some text and continue in other application
3. wait some time (1-2h)
4. Text editor is not working any more
5. check internet connection to be sure

this is the screen:

A forced closing of the app and a restart work. The app in the background seems to work properly (pictures taken in the meantime were uploaded).

Reasoning or why should it be changed/implemented?

When I click on the 3 dots, the menu at the bottom opens, but nothing to close or return to the main menu as I would expect. The retry does not work (not sure why).

It's funny that I didn't try to click on the "x", I will do it next time but it is nothing that I expected there rather in the right corner. On the 3dots menu... or am I the only one???

iOS version

14.3

App version

3.1.0

Server configuration

Nextcloud Version:
NC 19
Web server:
Nginx

Start by reproducing the text editor failure on iOS 14.3 with app version 3.1.0, following the steps in the issue and checking the three-dots menu, retry action, and close control. Done means the editor remains usable after waiting or provides a working retry or clear way back to the main menu.
