Cant apply play pass discount coupon problem.

You may face this problem if you have purchased a Google Play Pass subscription using multiple Gmail accounts. If you have an active Play Pass subscription on more than one Gmail, you will only be able to use the Play Pass discount coupons with one account. On all other accounts, you may encounter a "Can't apply offer" issue.

How to solve cant apply offer problem?

1. Try clearing the Play Store data and removing all other Gmail accounts from your phone. Then, attempt to apply the Play Pass offer again.

2. Try using the offer on a different device. This method works sometimes.

3. In some games, repeatedly trying to apply the offer might eventually work. However, it can take a lot of attempts—sometimes even hours.
