Change account in to buy in-app item

[SupportPlayPalace]

I want to change the account which is used for purchase purpose, but when i change account in Play Store and return to my app, it still uses my old account. Does anybody know how to change account for buying item in game?

he app will buy the in-app purchase on the account the app was installed to. Uninstall the app, change the account in the browser, install the app, then it will do the in-app purchase from that account (assuming you have that account in your phone).
