I use my olds VIRB as a dashcam powered by one usb port of all my ebike since my garmin 530.
On the Edge 530 and 1030+ the feature to start recording automatically with the timer worked perfectly, I'm not talking about the Widget, just the recording start configuration.
On my 1040 Solar nothing happens on Virb when the timer is started, although the configuration is correct, see image below.
Tested with Beta 14.14 and 14.15, and 14.50 with garmin Virb Ultra 30 and Virb360
This is a very important feature for my safety and before the 1040 Solar I just get on the bike, start my journey and I was sure that Virb was recording my entire trip.
