I'm seeing a problem with VivoActive 3 not being able to connect to a Generic ANT channel in a CIQ data field. It will connect one time immediately after the data field is installed, but then not again. Turning the watch off and back on does not fix the problem. No amount of waiting fixes the problem. The only fix is to re-add the data field to the display. Then it will connect one time and not again.
We may have had this issue on another device previously but I was not able to find documentation of it.
Here's a video that shows the problem.
The VA3 has firmware 7.30 which is current.
