Mine has stopped working altogether as well after updating to Mac OS 10.14.4 and WatchOS 5.2. I have rebooted both devices several times now, reset wifi and bluetooth, and tried unpairing and repairing but nothing is working.

I had this issue once before, a few months ago, and can't recall what the definitive step to fixing it was. The one thing I can offer that you didn't mention is signing out of and then back into your AppleID account, possibly on both devices (although you can try it one at a time).
