Microsoft Flight Simulator 2020

I have owned the MFS 2020 Deluxe version since it came out. After learning the update ropes for the program, I have been able to play FS on three of my PC's. I am attempting to play FS on one of these PC's and when I start the program, I'm greeted with the following pop-up dialog:





When I click OK, it brings me to the Microsoft Store, but a FS update is nowhere in sight. I then type my version in the search field, but it still does not produce an update. Here what I have done: I signed out of my account, closed Microsoft store, rebooted my PC, re-opened Microsoft Store and then signed into my Microsoft account again. I restarted my copy of FS, but it brought me back to the same pop-up dialog image attached. Am I missing a step here? Any advice for a fix would be appreciated.

Thank you. NealO
