You might try several things.
1: Make sure you have a fast internet connection. No matter what device you use, if the connection is slow it will cause the meter to not respond correctly.
2: Clear the cache on the phone. A simple restart should work. This will allow the loading of the game to it's fullest, thus providing a smoother play.
3: Delete the app, clear the cache, reinstall the app. It's possible that app didn't install as desired.
4: If all else fails send WGT an email with the problem. Be sure to include the type of device and OS that you are using. Android 9.0 is pretty new and they may not have all the bugs worked out for the game to be played on it. Letting them know your issues will go a long way in making it work.
