I was unaware that these applications are no longer supported. After the recent update they have vanished.
I have two questions. Is there some alternative application to use instead and how do I retrieve the data that those applications held?
I have seen the article showing how to re-enable them. I’m not very experienced with Docker. Fortunately my eGroupware installation is in its own VM. I’ll clone that and test re-enabling those apps before I risk my production system.
