I'm also suffering app freezes when playing 'free' credit videos. Have also had a some reports from mates in our country club. I'm on Android, freezing happens on my OnePlus 3T and also on NoxPlayer running on Windows 10.
It seems from one update to the next some bugs may get "fixed" at the expense of other bugs emerging or, worse, re-emerging. Too bad the mobile app forces you to update when there is one available, but I understand the design.
As usual, we'll see what happens.
