Roon Remote 2.57 on Android 16 (Pixel 9a)

For some time now (I can’t say when this started) when switching back to Roon Remote on my phone the Roon screen is partially blank (the three bar menu is visible as is the track) and unresponsive. Clicking on the central screen or the displayed track does not respond. I can pull down the menu and select Home and Roon resumes displaying correctly. This is obviously not the desired behavior.
Can anyone suggest an explanation? An Android setting? Something else?
