Issue with classic groups - anyone still using them?

Content

Is anyone out there using classic groups, still? We've been having issues with ours since a maintenance update in January that has basically made assigning training in bulk via groups impossible. The SR that I have logged has been given a *tentative* release date of 19A - which is at least a year away. Frustrating is one word I have used to describe this.

Is there anyone else in the same boat having issues with their classic groups?

Thanks -
