First, you need to understand which platform you subscribed to and how you paid. This information is important because subscriptions are managed especially by the platforms that are responsible for them.
If signed up, using your iPhone, Apple is responsible. If you signed up for Android, Google Play is responsible. If you signed on the Web, Pagar.me is responsible. The three platforms are different and generate different charges. However, there is a pattern of waiting times in the validation. Let's go to the details!
iOS
The subscription must be validated a few seconds later, but this may not be a rule at some point. If it is not validated in a maximum of 1 day, try to follow the steps in the article I've just subscribed to but I still don't have Premium access, what can I do?
Android
Android subscriptions have the same time pattern when it comes to validating them. However, it is more common than on this platform it takes a little longer. If the subscription is not validated within a maximum of 1 day, access the article I've just subscribed to but I still don't have Premium access, what can I do? and follow the steps.
Web
On the web, the payment is generated by PayPal. Likewise, it can take up to 1 hour for the subscription to be validated. Otherwise, access the article After payment. I've just subscribed to but I still don't have Premium access, what can I do?
