Is this the first time you’ve seen this error? (Y/N) : Yes, After the Update + reboots

Steps to replicate it: everytime

TY very much!!! Manuel

the app is probably disabled, which is because it isn’t released for 19 yet. You can either wait for an update (I know they are working on it), or install the Collabora Online app which is already avaiable.

best share what it says in the log, maybe there is a hint.
