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 :)

Getting your FD as close as possible in the big/small setting will allow you to adjust the small/big much better.  Also if you're pushing the  cassette beyond 11-32t, using Ultegra 11/11t jockey wheels is highly recommended.

I found the best shift combination to be Shimano chainrings, chain and cassette. With aftermarket cassettes, I found better shift performance with KMC chains. I don't particularly like the LTwoo FD. When the new ER9/X components come out, I'll definitely look to try the new FD out (if I can buy it separately) since it has a new design.

Sticky buttons on right shifter happened again! Went out and rode in about 32 degrees Fahrenheit and the right shifter got stuck and this time it stayed stuck the whole for the whole ride. Used the app to swap the shifters so left would shift the rear but still with the crosschain protection setting, I was stuck in the 3rd biggest cog in the back and the big ring up front as my lowest gear and there were quite a few double digit climbs today. I guess I needed to do some low cadence work anyways but dang I would've liked to have had a say in it...

I saw on YT that someone had a similar sounding problem. had to do with the little springs that actuate the button / paddle being misplaced, i think there are 2, and if one jumps out, problems happen. It looked fairly straightforward to open the thing and put the springs back in place. Can't remember if it was the nero show, trace velo, or some other channel.
I'm currently getting poor shifting quality, but i think it's because i m using thick winter gloves and i dont really know where i'm pressing.

Got another bike with shimano and it takes a while to realise I have to press alot harder on shimano. These things are so soft to shift.

I actually did that same spring fix last winter when I first encountered the problem. Something else is happening here. Put the bike in the house for thirty minutes and then shifting came back once bike warmed up.

LTwoo seems like they're trying to clear out 1st gen ER9 inventory, the new ER9 has already been shown paired with the new TT levers. I think the 2nd gen ER9 will be much better, especially with my experience using the EGR. The EGR shift levers are that much better especially with button haptics and being slightly longer. Also water isn't an issue. I wash my EGR gravel bike after every ride and have been caught in a rain storm.

One thing I've noticed having talked to local cyclists in China (on social media), LTwoo isn't popular there at all, with complaints about ergonomics and reliability. It seems most cyclists in China prefer Shimano!  ;D

I had a warranty claim that was handled by 80 Designer store last year because of a phantom drain on the rear derailleur after being caught in a rain storm and was pretty happy with how smoothly that went. That said, i'm pretty annoyed with this sticky button right now. I may be tempted to try out the EGR for my next build or a new ER9 if they release it in time but i dunno. Like I don't mind troubleshooting things and figuring things out but reliability is definitely important on my list.

I have zero complaints about the EGR. The better weather sealing, brake calipers, shifters and RD performance are all much more refined. I paid $300 for my EGR.

Yeah 80 Design store is super legit. At this point, they're LTwoo's international warranty and customer service front!  ;D

are the ergonomics of the EGR and ER9 brifters the same? Like can I just get an EGR right shifter and it'l feel the same like my left ER9? hahahaha
