No ban thankfully, it was only for a few seconds the mistake was made.
I have done some reading and see that to activate dual login it is required to have zero active subscriptions.
It seems that pausing these active subscriptions is not enough to allow dual login activation?
So, 2 options:
(a) allow them to finish and then purchase dual login.
(b) email moderator to cancel subscriptions, credit will go back to account, buy dual login.
Hope this helps others not make the same issue.
thanks a lot for the support
