I have chain dropping issue when shifting on the large front ring.
If i set limit so that it just raises chain to the largest rim it still jumps often over it.
I’m starting to think there have to be something wrong in my FD. At least that software limit is a joke, if this should ”limit” derailleur like that. See linked video.

It moves even more when chain is off. Now movement is limited by hitting a chain and ring.
in my experience, and i hate setting FDs with such passion, it's because you're incompetent. Like it's virtually never the FD's fault, it's almost always because you dont know what you're doing.
I've installed 5 ER9, and when set / INSTALLED properly, it works fine, there's no evil leprechaun hidden in the software playing with your mind and dropping the chain to spite you.
i have almost thrown bikes out of the window multiple times because of FDs i couldnt set properly. then after not working long enough, it ends up working and you're like "oh, thaaaat". and then it works. And sometimes there's no ah ha moment, but it just starts working, because somehow you fixed it and you dont know why.
So, keep grinding, you'll probably figure it out
