Hi @curisde! You can cancel your subscription by going to the Manage your subscriptions page in your Opera account. Pressing Manage next to your VPN Pro subscription will take you to our payment provider's website where you'll find the option to cancel your subscription.
If you originally bought it on Android, cancelling needs to be done on Android too, as it requires being logged into the Play Store account associated with your subscription.
If you need a refund, you can contact the payment provider, or VPN Pro Customer Support via: chat (open it by clicking the blue Support button in our Help Center), Help Center contact forms, or email.
Make sure to contact us from the email address associated with your subscription! If you bought your subscription on desktop, it should be the e-mail address associated with your Opera Account at the time of subscribing. If you subscribed on Android, it is the address associated with your Google Play Store account.
@justpaulo I have the same issue. I don't think I've even ever used Game Maker but I just tried and I cannot sign in due to the fact that it keeps saying "Your Opera ID is linked to another account" whenever I try to SIGN IN to Game Maker...
