I’m on an iPad Pro (2020) 12.9”, running iPadOS 16.5.
When I use Scaler 2 in Logic, the UI scaling doesn’t work properly. In the smaller AuV3 view, most features are not visible. When the AUV3 view is made more full-screen, the app UI lags pretty badly, taking 10 seconds or more to adjust to the proper size.
