So where's this update then? The post is saying 100% rollout but I'm unable to coax my watch into finding it and Connect says my watch is up to date on v8.0.
Check the autoupdate settings on your watch. Personally, I just did it via Garmin Express rather than over the phone, and it found the update straight up.
Thanks all, auto-update was enabled and previously working. GCM didn't work at all so in the end I installed Express on the laptop. It looks like Garmin have finally fixed the bug where Express wipes the watch settings when you add it though so wasn't the pain I was expecting.
