Bug description

I have opened an issue in the iOS NextcloudNotes repository here. The issue in itself, is that the note won't open in the app, however the final error happens in the DirectEditing Manager, here. It seems that the Manager checks if an editorId is present in a list of registered editors when opening a note, but the check fails and raises an exception because the list of editors seems to be empty. This error does not happen when using the offline mode, nor does it happen when using the Android app.

The issue relevant for this repository here, is whether one of the last updates broke the workflow of the iOS app. A look through the changelog did not show anything like that.

Steps to reproduce

Try to open note through iOS notes app.

Expected behavior

Note opens.
