If you try to make a purchase but it won’t let you because it defaults to the wrong Google account you will have to switch payment account.
Here is a step by step guide on how to achieve this:
FIRST, make sure that the wanted Google account has been added to the phone. Check this Help Center article if you need instructions on how to do that.
SECOND, make sure that your progress is safely stored in Google Play:
- Open the Google Play app on your device and log into the right account
- Open the game, and enter the in-game settings
- Press the Google Play sign in button to connect your game to Google Play
LAST, re-download the app with the correct account:
- Uninstall the game from your device
- Open the Play Store App and go to settings (3 lines on the top left corner)
- Make sure the account showing here is the wanted payment account
- Re-install the game
- Launch the game and try to make a purchase. The displayed payments account should mirror the one used during the game installation
