New bike with di2 12 speed. First couple of weeks everything worked perfectly. I now seem to be stuck in full synch mode. As I rotate through the modes (double pressing the button) I cycle through the blue light being on, double flash and triple flash, but not matter which it always operates as full synch. That is when I shift the chainring, the cassette gear does not change. But if I go to 1st gear on the cassette the chain ring shifts down and the cassette shifts up 3 gears (and vice versa). Had the bike for about a month so I may be doing something wrong but I'm fairly sure the first 2 weeks I tried all 3 options and they all worked as expected.
The first weekend I connected vie phone bluetooth. I don't think I made any changes and it also worked for a couple of weeks after that so fairly sure it's not that.
The battery did get VERY low (it must have been delivered at <10% ) to the point the cassette had power to shift but the chainring didn't. I have fully it charged it. It is around this time it stopped being able to change modes but maybe be coincidence.
