I have a 13 Pro and AT&T. I have never had the “5G+” appear and have my connection work correctly. It either drops my speed to a crawl (speedtest will report 1Mb/s or less and things will load at speeds that seem to rival EDGE) or I completely cease getting internet despite it saying I have several bars until it returns to the regular 5G icon. I have a friend with AT&T who has had similar experiences, but he doesn’t live near a MMWave tower so it doesn’t come up much.
I have had this experience in several different states, including most recently New York. It actually happened even while I was in the process of typing this post on a train.
