New problem with iOS/iPad app running on M1 Pro MacBook

I realize that it's not really officially supported, but I am running into a new problem running the iPad/iOS Channels app on my Mac (M1 Pro 14" MacBook Pro, macOS 12.3).

When I click on the Guide to watch a program, the program starts, but the controls at the top of the screen and program description at the bottom of the screen stay layered on top of the video and do not disappear after a few seconds like they used to.

I can get rid of them by clicking PiP but clicking PiP again brings it back inside the window and clicking on the window does not bring up any playback controls. I have to quit the app.

Has anyone else run into this and is there a solution? TIA

This has been fixed in latest TestFlight beta.
