Restoring purchases
If Paste fails to restore your subscription, make sure that you are logged in with the same Apple ID that you used to purchase the subscription on all devices, and that the subscription is active in your account.
Please also make sure that you’re using the latest version of Paste (version 3.0 and above).
If everything looks good but Paste still fails to detect your subscription, try to delete Paste and re-install it from the AppStore.
