Airdrop not working on new iPhone X

I have a new iPhone X, running 11.2. Airdrop is not working (hasn't since I set it up two days ago). On the 7 I came from, it worked.

I also upgraded my wife's iPhone 7 to 11.2 and airdrop no longer works.

I have followed the steps suggested in various forums (log out of icloud, reset network settings, force restarted, etc), but no luck.

Any help/ thoughts??
