Hello,
I just did upgrade Nextcloud Office of my Nextcloud Hub 3 (25.0.9) and Collabora Online CODE docker instance 23.05.2.2 under Univention Server 5.0.5 from Version 7.1.4 to 7.1.6 as well as Collabora Online CODE Server app from to version 23.5.104 to 23.5.301.
Now on my Android phone in Nextcloud-App Office Dokuments .Doc don’t become opened but downloaded instead and I get asked to select an Android app to open the file.
If I downgrade both Nextcloud-apps to the previous versions it works again.
In Firefox Browser open and manipulate the same office document still is working.
Are there any other useres with the same issue or is it my own local problem?
