I'm having the same problem, the play button is behind the taskbar and covers all the other buttons there unless I set the taskbar to hide automatically. we also cannot resize the app vertically, I did some troubleshooting like changing my screen resolution but nothing happens. still waiting for an update to fix all these problems.
