We had to do a server update earlier today and I had a small configuration issue. The background task was not processing the last few hours and I've corrected that issue.
There was a glut of notifications that were off by several hours.
We also had an odd incident where an Author group expired. If this happens to you, you can just go back to the store and select author again. (In theory) If there is an issue, just send us a support request from the help menu.
