As described above. Unfortunately, neither Collabora loads in the app (Android and IOS), nor is another submission form still possible then. Unfortunately, neither Collabora loads in the app, nor is another submission form still possible then.

What have I done?

• I have created an exercise in a course. I have enabled Collabora and file submission as possible submission formats.

What am I expecting?

• I expected that students would at least be able to continue to submit files via the Moodle app. It would be better if they could operate both types of submission via the Moodle app.

What happens?

• Unfortunately, file submission is also no longer possible via the Moodle app, so students can no longer use the app to complete their assignments. I am attaching a screenshot of a student. She then uploaded the files that can be seen in the screenshot via the browser.
  

What version of Collabora do you use and also is it a dedicated server or a docker container?

• I've been using collabora 6.4 as this bug occurred (just upgraded to 21.11 afterwards - see other bug regports) on a dedicated server

What version of Moodle and also what version of Collabora-Plugin do you use?

• Moodle 3.11.4 and Plugin-version v3.11-r1 (2021102600)
