A lot of us were discussing that a lot of ESO PLUS's issues might be resolved by it properly being added to the Xbox Store rather than being there and being hidden. Well it is now in the Xbox Store and I anticipate a lot of users renewal dates come at the beginning of the month and I would be interested to know if your missing Crown and other issues associated with ESO PLUS might be resolved or mostly resolved.

It also seems to allow the use of redeeming a code for ESO PLUS at least from the ESO PLUS page on the Xbox One console itself, which means we may have the option of eventually being able to purchase retail codes like the PS4 allows. I am really hoping this resolves the issues with ESO PLUS or at the very least allows for sometime in the near future for it to be fixed. Well I only saw it today, although it could have been there before, so if you have a renewal date soon it may or may not help with it right away, especially if it's still being worked on technically.
