I'm in actiity 1, When I want to move an app to activity 2 (clicking right on Only-Icons task manager -> Show in Activities -> (there is a tick next to activity 1) -> I choose "Move to 2") and the app is NOT moved, but now it has ticked "All Activities", so I have to do "Move to 2" AGAIN, and then it lands in Activity 2. BUT... if i do the same actions from the app titlebar, it works correctly.
i think that's a duplicate of https://bugs.kde.org/show_bug.cgi?id=483148
Yes, it is a duplicate of that bug, well-spotted. I'll try to have a look. *** This bug has been marked as a duplicate of bug 483148 ***
