I have the 12 speed dura ace di2 9250 FD and after all the adjustments with the Etube app it will not shift into the big ring when it's supposed to. When the chain reaches a small cog where it would usually jump, it doesn't. The FD makes a small move but it doesn't push the chain all the way over.
55/42 chainrings fwiw
Any help would be appreciated.
