All right, I now see that the downloadable PC version works just fine; it's the browser version that's at fault (either that or Edge 99.0.1150.39 or Win10 21H2). Thanks and sorry, I should've tested that earlier!
I tried Edge on Win10 and it still works for me. Don't know what's going on but glad the desktop version works for you.
We'll see if anyone else has the same issue.
