Running XenForo v1.1.1 I have an active account upgrade configured which is a monthly recurring PayPal subscription. The account upgrade adds the user to another user group I have set up. The process half works: the user can go to account upgrades, click subscribe and the then sign-in to PayPal and successfully set-up the subscription and I receive the payment. However, they are not added to the group I have specified in the account upgrade. Manually upgrading their account does work however. Is this a known issue?
