How can I pay for Guru version other than with Google Wallet?
The only way for me is to sell the Guru version via Google Play Store, in order not get banned by Google, as they get 30% of the money and don't want it to go elsewhere.
Please look through accepted payment methods in order to choose what suits best for you.
Also the app is available on Huawei App Gallery.
