also mine is 2x11 53-36 and 11-25. I will give feedback if something tell new this support .

Edit:///
Today chat with store and fianlly nothing new, same info  like
"When changing gears with shift, the crank needs to be cranked up, otherwise the RD will flash a red light and not move."
It's very hard to talk with them ;/ now again I'm waiting for any response ;/
Today I will also test with another battery, maybe there is some drops of Voltage ?? FD need more power to change gear i think

Thats me and nope no solution yet. Just for saftey reasons that i by mistake shift both exactly at the same time i put my charging cable and a usb-a to ubs-c adapter in my saddlebag, so i can connect the rd to my phone as a charging device and get it working again.
Maybe some pseudo "calibration" needs to be done, because mine thought it was in the smales cog altough it was in the middle of the cassette

you run 2x11 or 12? Yestrerday I was testing and with gear protection off my system go down after only one change from 1 to 2 at front, with gear protection on this situation happend less often. I think this is connected with some adjusment of FD, when shift on front is smooth then is ok, when not system is blocking.

I'm in contact with Ltwoo and Store from aliexpress ,but damn, they are silent ;/ Support even not exist

Could somone whith 53-36 on front take photo of FD when is at second gear ( now mine is set with sticker 3mm up the tooth) and screen with calibration for FD on 1 and 2 gear (i know that this depends which frame, hanger etc.)

//Edit: I have contact with a few people with Ltwoo and I have tommorow video call or chat with someone from tech support, will see

Sory for post my problem again but this is new er9 from Aliexpress, ltwoo and store from few days are off ;/ Total silence od ther side ;/

problem with er9 one of you have simillar problem (i have PM him).
straight road without any holes, and system go down. This happend with some combination of front from 1 to second and on rear and back. After plug charger system turn on (new battery). happend when i tried to shift both derailleurs at the same time??
Front from big to small and back vice versa.
Yesterday i have test it without gear protection in app (off) and while on FD move from 1 to 2 then all OFF. When gear protection is on i can change at FD gears few times and when chanigng in not smooth system of, this looks like some of protection?? In my opinion FD is quite good adjust at 2x11

53-36T and 11-25T

Thanks for any help
