I followed your instructions, it worked for a few seconds, then went dumb again. Tried the next suggestion of using the space bar to maneuver, it came alive for a few seconds then dumb again. I've used Mac products since 1988, and I've never encountered the kinds of problems I've had with the 4 new Apple products bought a month ago. This is the iPhoneXR, but weird things happen on the new MacBook Pro, and the watch. The iMac Air is working pretty well, but that's because I mainly use it for art and a game or two. Suggestions?
I've exhausted all the support people; and thought you might have a work around for the Cursed Cursor in the note in my iPhoneXR.
While we are on the subject, maybe you have a fix for a jumpy, erratic cursor on the MBP? Odd that both of the most exasperating problems deal with the cursor!
