The patch seems to have broken this feature. I could move the wow window to my other screen with the default windows shortcut of “Win+Shift+left/right arrow” but now that doesn’t work.
I used that a lot when browsing while doing something in wow that requires low monitoring like camping a rare or something. I would just send the wow client to my side screen.
I’m adding my voice to the ring on this one, as I too am no longer (since the launch of TWW pre-patch) use the Win+Shift+arrow to move wow around to a different screen.
Also having this same issue since the pre-patch. Having to go through settings each time when launching the game is a frustrating extra step to have to go through when the Windows shortcut should, and always previously has, worked.
