Right now I'm a ESO Plus member and I pay monthly. I do this through Steam. I want to start paying every 3 months, but when I go to steam to purchase the 3 month it wont let me. Is it because my monthly is still active?
I believe the Steam membership system is reoccurring, I can't be certain, but I believe so. Now going by a few pages I've read it seems you'll need to contact Steam Support. I suppose you could cancel and then re-apply, but even then you'll need to contact Steam Support for cancellation.
