iOS App (v2.22.8) hangs immediately after start


in the last days the Nextcloud iOS app (v2.22.8) started showing some red messages warning that was unable to write on the WebDAV.

Now it turned that when I load the application, it directly loads and vanishes. Double clicking the home button I can see the app in the open apps list, but again, if I select it, it appears and vanishes.

I’m not sure if a reinstall will solve this problem, but I would like to ensure if a reinstall will keep the coherence of the iPhone gallery and the autoupload directory.

What should I do?
