IPhone Xs Max: app won’t work

Got the new iPhone Xs Max with iOS 12. The Roon app is unusable in that the buttons are tiny and they don’t respond when pressed. I tried uninstalling and then reinstalling the app, with the same result. Is this a known issue? Previously I had the regular iPhone X and never had a problem. Any feedback is appreciated.
