Run won’t sync?!

I did a strength workout (synced), run (WILL NOT SYNC), and a walk (synced) - in that order. I can see the run on my watch- but it will not sync over to Garmin connect. However, the other 2 workouts today did without a hitch.

I’ve done all the tricks. Hard restart. Uninstall/reinstall app. Bluetooth pairing. Etc.

Please tell me I’m not alone, and this is a global problem them are working on today (12/30).
