I purchased Litchi application 06.04.2022 in Google pay. It was working perfectly approximately one month. But now after entering become message :" Application not licensed. Please buy it in Play store." Play store has indication that application already installed, open or delete buttons. After pressing open button in play store, Litchi opens and gives same indication “application not licenced”.
I have try to delete application and reinstall it , but now play store ask to buy it again. The same android phone, the same google account nothing were changed.
