I had purchased (and was charged for) a month recurring sub. I was not allowed to apply it to my account yet because before I put in my key, I was still a trial account. After applying my Collectors Edition key first, my sub updated saying it would expire Jun 3. I was then able to apply my purchased subscription credit to my account, which updated my expiration date to... Jun 4

One extra day for the cost of a month haha. Contacted support chat and all they could tell me was "we're fixing it, hang tight." Hope they fix this soon. At least I can play in the meantime..
