This is the error. I have tried changing the country settings too. I use one google login id for the Diarium app while the Play Store default email id is a different one. I have previously bought apps on PlayStore so this is kind of weird.
Given I use a different google id for Diarium, to my default play store email id, could you help me understand if this is going to be an issue? I don't want to be in a position where I eventually make payment on Google play store, only to know that there's an issue with using a different email ID. Given the specific situation let me know if I should directly write to you.
