Yes, I have the same problem.. It is Saturday morning, and I still do not have the new EW with Mindy Kaling on the cover on my Nook hd+... I checked, and last week's issue was not a double (2 week) issue.
Same problem here. The store shows the new issue, but there doesn't seem to be a way to manually download it. I've also tried syncing, turning Nook on/off, etc., with no success.
I am getting a notice in my Nook's Account Settings that "Sync is currently experiencing problems. It will be back shortly," but I'm not sure if that is the problem, or if it just applies to Google+ (which is showing a "Sync error").
I had the same problem but mine showed up yesterday evening.
