I can not use the calendar & contacts app online. As you see on the screenshot, the icons were not shown and when i’m clicking it, i the only a white blank site. My clients (ipad direct and some adroid’s with davx5) can use it mostly, sometimes it hangs a little bit.
I deactivated the modules and reactivated it, nothing.
Updates to the last nextcloud version, nothing.
I had the same problem with the note app, but there were in the past an app update and since this time, this app functions correctly.
Did someone have an idea? I don’t want install all completly new with all clients and data.
Question: is it possible to deinstall the apps and reinstall this with no dataloss?
P.S: Sorry for my english Answers in german perfectly
