Same issue here. I didnt notice until last night when i log in. I have my crowns from the previous month, and it is showing as still active. Mine renews on the 26th of every month, so hopefully it is sorted out soon as I have no access to the DLC and that makes me not so happy.
It was sorted out and had nothing to do with ZOS. It was M$. There was a service alert on their services page stating they were experiencing a problem with the download content service. EA Access members/users were also effected. ESO+ is active on my account/character again as of early this AM.
Well...at least MS alerts people and admits when they have issues with their services. I've yet to see any official response from ZOS or even from a forum mod that there are regular issues with their ESO+ service.
Second month without my 1500 allotment of crowns. Last month I'm paying for ESO+.
