Universal Clipboard hasn’t worked in many months, and reminders won’t sync until I actively EDIT one on one device (and that may or may not propagate to the other devices). It used to be awesome and now it’s extremely irritating. My devices don’t respond anymore to changes on other devices. I’m another person constantly suffering the WONT SYNCH nonsense of iCloud’s “it just works”. Did all the well-educated GUI and user experience experts leave Apple when Jony Ive put the print marketing department in charge of re-skinning the UI?
Seeing the above (I’ve not “upgraded” yet), is informative and exasperating.
