After completion, I got a message on the screen.
Your update to MCMIS has been received. Then below it informs me you may want to update your operating authority with the address. What?
Then in the Alerts section, it says that my address must match with the one of authority. What I did is add four numbers in the zip code to match the one below for the mailing address. That is all. Maybe I shouldn't have done it. So, I went back and reverted it to what it was. I have two alerts saying the same thing. So, I will give them a call tomorrow to see what they actually need.
