If anyone still faces an issue with Advantage Membership, please post to this Forum. Let's use this thread to report any issues with Advantage Memberships. Please do mention your successful PayPal transaction ID while reporting the issue.
This seems to be a recurring problem so I would suggest asking a Moderator nicely to make a new category in the "Help and Questions" section as this thread is in "New Users".
If you want all the activation requests in the same thread then you or a mod could start one in the new "Advantage Problems" category and make it sticky.
This new category could also be used for when the Advantage image queue goes bonkers and people want to whine about it. lol
