Universal Clipboard doesn't work anymore First time I've installed Sierra a couple of months ago, I tried the universal clipboard with my iPhone 6. It worked immediately like a charm and since I used it, I found this feature really useful for many use-cases.

Unfortunately, this feature doesn't work anymore after I upgraded from a 2 year old iPhone 6 to a new iPhone 7 Plus.

I know what I need for that feature to work (as it used to work fine):


Both devices are connected with my iCloud account (same Apple ID)
Bluetooth and Wifi are turned ON on both devices 
Both devices are connected to the same Wifi network 
Both devices are next to each other (less than 1 meter). 
iMAC 10.12.3 (16D32) 
iPhone 7 IOS 10.3


Both iMac and iPhone have been rebooted a couple of times.

No text, no URL, no picture can be copied &amp; pasted from one device to the other anymore.

Any thought what could be wrong with the new iPhone 7?
Turn continuity (=handoff) on for both devices, and also make sure they are logged into the same iCloud account.
