Vivoactive 3 s/w 6.60 just hit my watch

Please let us know if you get a real response. My wife's VA3 is suffering from the exact same problems and makes the watch completely useless. I really don't want to RMA the watch for a simple firmware bug.

All they mention in the Release Notes for 6.60 is: 

Changes made from version 6.10 to 6.60:

• Bluetooth connectivity improvements

When I get home tonight, I'm going to try unpairing and removing all Bluetooth devices from the watch then repairing and see if that makes any difference. Just turning off Bluetooth might help diagnose if it's a Bluetooth problem.

it's horrible after updating SW 6.6, batter lasts less than 18 hours!!!!

terrible battery drain with this update. I'm charging my watch every day or two. Before it could go a week without charging! I hope they fix this quickly.

Anyone have GPS issues? Always on Wait for GPS on mine, only had v3 for 2 weeks.

does any of you have BT connectivity issues before that the new update solved?? mine lost connection to the phone even when they were near... is BT connection more stable with the new update??

Lost HR and had to go into settings to reactivate it.

Sw 6.6 watch now lasts 10 hrs at best, my third and likely last garmin I will buy . The watch has not been worn since this upgrade. Garmin you have caused this problem and now ask for money to repair! not acceptable 

I have Vivoactive 3 Music s/w update 4.5, which I think is the same as the 6.6 discussed here.

I noticed my GPS distance/elevation tracking is now reduced for the same trail.  Previously my distance/elevation data will be very close to other users (mostly other Garmin devices like Fenix or Edge bike computer.  But now I would say the distance is 5% less and elevation is 10-20% less than before and with other Garmin users.

Is this error in tracking or will other Garmin devices get a similar update and their distance/elevation measurements get reduced?
