Garmin Vector Powerdrop

I don’t know if this is a Garmin or a Zwift issue.

For the last 4 weeks I have been using Garmin Vector 3S pedals to connect to Zwift. For most of those 4 weeks it’s been fine, until 2 days ago I started getting powerdrops. I’ve updated the software and replaced the batteries (only 25 hours use, Garmin claim 120 hours between changes). Has anyone else had this issue and did you solve it? I had to abandon a race this evening as they started dropping out every couple of minutes, very frustrating.

ANT+ or BT?

If ANT+, using a usb extension cord?

Using wifi or cable for net connection? PC/MAC or Apple TV?

if PC/MAC, could you upload your game log file somewhere and link to it, so I can look in the log file and see what’s going on?
