Uh oh now I have a new problem. After installing the assist buttons, my left shifter is essentially dead — doesn’t do anything. Even the top button doesn’t change Garmin pages.
When I go into the e-tube project software, I see my two shifters. My goal for the left is to have the larger paddle downshift the rear and the smaller forward paddle upshift (reversing the right shifter, like an eTap setup). In the software, I can only program the right shifter. The left shifter just says front shifter up / down or some nonsense since I have no front derailleur here. Is this a side effect of having these new assist buttons? I did not have this problem when using the Levo controller.
