I am trying to determine if what I'm experiencing is an isolated issue or not.
Recently (last 2 weeks) I've found that if I do a "suggest page to friends" and select more than 50 friends at a time per day that the invitations never actually arrive on the corresponding profiles. The box says that "invitations have been sent" and the person is then greyed out in the box, but when I call the person that has the profile the invitation never arrives. I've tried this by selecting all the friends, 100 at a time, and 50 at a time. When I get down to 50 at a time then the invitations start to arrive.
I started to notice this when suggesting a new page to friends and there was no action on the numbers (close to 5000 friends) a couple weeks ago. Previously I'd see movement on a new page within 24 hours (depending upon the market for the page the movement would vary but would still be there).
