Di2 shifting, is not enough micro adjustments?
Canyon Endurace 8.0 Ultegra Di2
Medium cage derailleur
originally came OEM with an 11-34 cassette
I put on an 11-28
Issue - I cannot get the gears indexed right. They shift crisply down the cassette to higher gears but are noisy shifting up the cassette. Once in the gear, it sounds fine though I should add.
I have checked hanger alignment with a professional tool.
One strange symptom is that at -16 micro adjustments the chain and cassette aren’t noisy. They should be? And then you adjust +4 clicks and then test, according to the manual.
11-34 cassettes come with a 1.85 spacer from Shimano. Could it be that the new cassette is sitting too shallow? 11 speed shouldn’t need a spacer...

Thank you!! Thinking I should I try a 1.85 spacer for starters. If it's too much, I assume when I tighten the cassette it won't tighten right.
Are there any other causes of noisy shifting up the cassette? Again, once it shifts, it stays in gear, but it's noisy shifting up. And I've played with the B-screw a bit with no luck.

Someone corrected me in another thread yesterday. The 11-34 requires a spacer, but he said the 11-28 does not. (I only use 11-34T, so I falsely generalized). If the 11-28 came with the spacer, then it probably is worth trying. If it did not, then almost certainly it is not required.
Another thing is the chain might be on backward. The lettering on the plates should be facing outward (and if you have a quick-link, you need to pay attention to that too, although the latter wouldn't likely be the cause of your issue).
Because of my frame, my derailleur centers around +14 clicks, which I find annoying. There is a way to re-zero it, but I have never been able to figure it out.

Check you chain length...going from a 34 to a 28 is a big drop, so you'll probably have to remove a link or two.
