App Won’t open on iPhone 11. Watch app problems too..,

The app was fine on my iPhone 7 but won’t get past the initial splash screen on iPhone 11. After about 10 seconds the app disappears but is still running in the background. Resuming the app shows the splash screen for another 10 seconds. On the apple watch 4 running watchOS 6 the app won’t allow me to end a tennis session. Pressing the END icon causes a short beep and the session continues, never syncing with the phone. I reached out to support via twitter and received no response. Help!

Is This a Joke?

I bought this app for $10 because I didn’t want to upgrade to the new Apple Watch Series 7 in order to get the new service speed feature. From what is described in this app, it is supposed to measure your service speed. This is misleading. You basically have to play an entire set or games and then it gives you an average speed which is totally inaccurate. I do not recommend this app. Save your money!
