RevenueCat SDK
Warning
If you don't have a login system in your app, please make sure your one-time purchase products have been correctly configured in the RevenueCat dashboard as either consumable or non-consumable. If they're incorrectly configured as consumables, RevenueCat will consume these purchases. This means that users won't be able to restore them from version 9.0.0 onward.
Non-consumables are products that are meant to be bought only once, for example, lifetime subscriptions.
