Greetings, upon clicking the icon, a message stating "application not installed" appears. To launch it, I am required to visit Google Play. Any guidance on resolving this issue would be highly appreciated. Thank you very much.

Is the iReal pro app installed on the device you are using?
When you visit the Play store (as directed) does it show the app as purchased?
Make sure you are using the same login/account you used when you first bought/installed the app.
