I have the same issue with backlight gesture after update to 7.6. It doesnt work in any settings. (During activity, in watch mode, after sunset, gesture only). Previously, I used backlight gesture after sunset and works properly. My previous fw was 7.56 beta
Today, i try everything. All possible gesture setting combinations. Backlight on key pressed works fine, but gesture option still not working. Finally, I tried reset watch to factory defaults and setup it again. Doesnt help :-(
I am running SC8 watch face but that was fine before update. Could be certain batch or something we have in common. my firmware 7.60 (ad329d1) unit id 3957130315
