Used a new Apple Magic Keyboard with my 2018 iPad Pro 12.9” (iPadOS 14.0.1) without any issues for the last couple months...until today, when the trackpad stopped working and the cursor disappeared. Restarts and reattachments didn’t work...while the MK remained plugged into power. Fortunately, I found this thread (thanks all!), unplugged the MK, restarted and reattached the iPad again, and the MK trackpad & cursor are back. So, an MK power cycle was the key to working around this Apple bug. Apple, these threads show this problem has been going on all year, in both iOS 13 & 14...past time to squash this MK bug!
For almost 2 years I used the Apple Smart Keyboard Folio with my iPad Pro, but it started producing “Accessory not supported” errors, requiring a restart/reattachment each time. Apple Support had me do a full iPad reset/restoration from factory defaults—didn’t help. Got so frustrating that I finally upgraded to MK (which I liked much better, until today). So, I guess, “well done” Apple?! :-/
