It is too late to do anything with pairing with Windows 11. One of Microsoft's moderators said that the drivers in Device Manager were faulty and wouldn't allow pairing. He suggested that I use a Bluetooth Adapter. For what I need to do, move my music on Windows 11 into my iPhone Apple Music, I can do that without pairing by importing the content into iTunes. Besides, today I noticed a bulge in the iPhone. At a Apple Store, a technician said it wasn't worthwhile to replace the battery. So, I will have to purchase a new iPhone. What makes me mad is that I tried to post something on this site about the battery, which lost its charge rapidly after charging; but the site would not allow me to post for about three days. That happened in two different browsers.
