BetterSnap Not Working on Rotated Monitor?

Been a BetterSnap user/fan forever. I decided to rotate one of my monitors. However, I can't set any pre-set window sizes or use BetterSnap in any way on the rotated monitor.

Is that supposed to work or is that a limitation of BetterSnap?

I'm on Mac Sonoma 14.5, running BS 1.9.9. Thank you.

that should work fine, BST doesn’t care about the rotation. What exactly happens when you try?
