I have $ 10.00 on my Google Play account (from Google Play vouchers) and would like to buy an in-app purchase through Minecraft PE. Can I somehow switch from Paypal to vouchers?

ps

Simply add the voucher in the Google Play app, the money is already on the GP account

But I have already redeemed the code in the play store, there are also 10 euro in my account, but I can't use them

ps

Then in the settings change the payment method
