I'm trying to figure out if this is a Community issue or if my IT folks have implemented some new security measure that's messing me up. I'm leaning towards the latter, since I'm having a few other issues, but I thought I'd check with you all, just in case.
When I'm looking at messages in Community, I generally go through my notifications list to review any updates on items I'm watching. This week, however, all I see is:

When I select See all notifications, I get a page that says "You have no recent activity." I know this isn't correct, since, when I go to my profile and look at a Question I started watching this morning, I see that someone has posted a response since I started watching it.
I tried logging out and back in, but this made no difference. On Friday, I did need to clear my cache and cookies for another reason, but I don't know why this would affect this.
And then, this morning, I did not get my daily digest email.
Has anyone else experienced this? Was there some behind-the-scenes change to the settings? Should my next stop be my IT people to see what they turned on/off?
