I just updated from version 126.96.36.199 (purchased in 2013) to the latest 188.8.131.52.
To my surprise users cannot buy more than one subscription.
I went back to 184.108.40.206 and found out that users can again buy one or more subscriptions, using the same account.
Have I done something wrong?
Is there a setting somewhere that needs adjusting?
And one more question: is there a page where a user can view the subscriptions he/she has already paid for?
