If you can’t see your upgrade showing on your account, try logging out and then back in to refresh things. Additionally, please make sure you’re logging in with the appropriate account.
If you paid via the iOS Appstore, try restoring purchases by clicking the “Upgrade” button on your iOS device and selecting the “Restore Purchases” button. If the purchase does not restore, you should see an error noting the email address the account is under. Log in with that account instead. If you still can’t see your upgrade, contact our friendly Support Bears for further help.
