CMD TAB doesn't move between apps in different spaces
I used to be able to used CMD + TAB to move between different open applications that were on different spaces but it no longer works. Control - arrow works to move between different spaces, but I find that cumbersome to use when I have multiple spaces open and have to cycle past a few screens to get to the space I want. I haven't updated for a while, but I know this used to work for me just fine, and I'm sure it still works on my iMac. I'm on macOS Mojave version 10.14.2.
There was a post on this back in Jan 2018 but it didn't seem to get resolved. Has anyone had this problem and been able to solve it?
Thanks
