On my Edge 840 solar with 18.25 beta firmware the Varia RCT715 controls and light network are not showing up unlike on my Edge 1040 with 18.25 beta firmware. When you go to the 1040 the Varia RCT715 shows as a tail light under light network. There is also another screen where you can take a photo or video. Neither of these options show on my Edge 840 solar.
