Hello, I will check that tomorow, it's time to sleep here in France. Please email me at support@quest-games-optimizer.com and I will help you and verify that asap after my night. Share me all the details you can like your device model and the email you used to be able to investigate quickly 👍
However I saw your bad review..., it's not pleasant to help in these conditions especially if you even didn't try the app.
Edit: I found your issue, the email you entered when purchasing QGO contains a typo => @gamil.com instead of @gmail.com. I will fix your account tomorow
