If you are unable to sign up for a Fountain Premium subscription, it may be due to the operating system you are using. For example, if you are on Android and using a non-standard operating system (such as Graphene OS), you may encounter errors when attempting to become a Premium subscriber.
If you are not using Graphene OS on Android and still unable to sign up for Premium, please contact us so we can assist you further. The more information you provide, the better we are able to help you. Please attach screenshots or a screen recording if you can.
