Group folders : Shared files are only downloaded instead of opening in the app

[osobo]

Dear all,

I experience issues with Group Folders. They are visible but their files cannot be opened (except by me with admin status), only be downloaded, despite giving users all permissions notably writing ones... Sometimes the folder cannot even being opened, only downloaded..

I don't know exactly when the problem started, this NC instance is still a work in progress with only few users. I only got their feedback recently.
I assume it may be related to updating from NC 28.x to NC 29...

Is there a way to repair / reset all users permissions for a certain group folder ?

If not, is there a way to revert back to NextCloud 28.x ?

I've unfortunately a 2 days backup scheme so I'm stuck with NC 29.0.4 for the time being

Thank you for your suggestions and support

Best wishes

Have you tried to search for this issue or how to reset folder permissions in the Nextcloud issue tracker or forum?
Do others here have had similar issue?

@nebulon Thank you. Yes, I did a quick search on the NC community forum but could not find anything recent. In some older posts where users mentioned similar issues, it was eventually classified as a bug and fixed with an update. I just wanted to ask other Cloudron users if they have similar problems (?) Time will tell...
