Confirming the same issue here. Universal clipboard breaks in the iPhone > Mac case (but Mac > iPhone seems to still continue working) Macbook Pro M5 Pro: macOS Tahoe 26.7.1 iPhone 16 Pro Max: iOS 27.0.1 Tested by logging the pboard activity using command log stream --predicate 'process == "useractivityd" OR process == "sharingd"' | grep -iE 'pboard|Received Ad' and trying to copy things on iPhone. When it's broken, you see none of the following which confirms the iPhone > Mac connection is working Received pboard available advertisement SFActivityAdvertiserOptionFlagCopyPasteKey = 1 Restarting the iPhone seems to fix this problem, as after the restart (after a bit), copying things from iPhone is able to be pasted on the mac, and you see these lines in the log. Turning Wifi/Bluetooth off on iPhone and Mac doesn't fix this issue. Only fix is the restart of the iPhone. Looks like the issue is a service or something breaks on the iPhone.
