Apps switch back to primary monitor when moving between spaces

I have a 3 monitor setup with a total of 27 spaces (3x3x3). Whenever I try to move an app on my 2nd or 3rd monitor to another space (using the keyboard), there is about a 50% chance that it will jump to my primary monitor.

Thanks for the report, I’ll try to reproduce it.

What space does the window end up in? (Is it the intended space, just on the wrong monitor?)

Hi, sorry scratch this entire thing.

The issue was that the key-commands were interfering with the same commands in Spectacle. So when I switched spaces Spectacle was also switching monitors. I’m assuming there was a race condition here which is why it was intermittent.

Ah ok! Thanks for letting me know.
