Yes I too just got 4 Moto tags which I'm unable to pair to my phone.
On a related note - they seem to require pairing via 'fast pairing' -- which also seems to be non-operational on GOS.
they most annoying part is, I could have sworn I got one to pair when I got it out of the box - I backed out because I thought I'd like to link it to another account and have since been unable to pair. I was only paying half attention so maybe I'm imagining that it paired...
I feel like perhaps the right settings in the right places could resolve the issue, but so far I've had no luck
