I bought my 2022 2500 used last Christmas in New Mexico and it had this message then. I took it back and they said they would have to take the cover for the center console off to debug and the parts would probably take a week or so. I had to hit the road but finally got it in a shop in CA. After a day in the shop they said I needed a new radio. After a 2 week wait I took it back and they replaced the radio. I still get the message, but intermittently and they said I have all of the updates as of today. Everything functions OK, but I wanted to get it fixed while it is still under warranty.
I have Ram Telematics and the wifi subscription and I have full functionality. If the dealer can't resolve it I'll just live with it.
