Hi Basj, Thank you for following up,
I'm not sure if you're suggesting you could or could not replicate the issue, but I've setup a few screenshots indicating the issue. Pictured in the screenshot are two monitors (same size, 1920x1080). On the left is a simple group, on the right is a new application (edge) which I will drag from the right monitor to the left monitor. The end result is the browser is added to the group, but the group moves from the left monitor to the right.

I hope this better illustrates the issue and that it can be fixed.
I should also note, I think if a Groupy group is full screen, when an application is added to the group, the app should go full screen, the group shouldn't be resized.
Thank you
