I’m using for in app purchase in my application - Soomla and Bluestack - for test my app , because I don’t have android devices now. When I test my app and want buy something in my app - I have an error - Authentication is required you need to sign in google account. What can I do for fixing this?
I tried this, in fact I tried 3 different users account on 2 different devices but the problem persists. Are there any other answers? 5 days and counting so far on this on for me and no solution in sight I’m seriously thinking about binning everything if the money pipe don’t work.
Remove google account from device.
clear cache of google play
then retry. it should work fine!
