LTWOO ER9- front derailleur--- not communicating with RD

[vito117]

Have the version V1.0 here.
So I removed the RD and FD to do some maintenance on the frame.
Kit sat on the bench maybe a day or 2.
Put it all back and now FD wont engage.
RD works fine. Shifters fine. Battery fine. Cables fine. Removed app. New account, reinstalled app, re-paired. Still nada.
Even took the FD and plugged it into another ER9 bike and it did work. So rules FD out.

So what the phuk would make a somewhat perfectly working fine set all of sudden stop communicating with one another?
Something in the RD since this is the brains of the operation.
Of course LTWOO service is worthless as tits on a boar to reply.

Any new on this issue?
I have a different, but similar, issue.
On my LTWOO eR9, my L shifter stopped working.  It works only sporadically, and generally with some seconds delay.
The Front mech works perfect from the app, so the mech itself is good. Battery changed in the shifter, no change.
I haven't found a solution yet.

In addition, I am annoyed that ltwoo seems NOT to sell spare replacement parts, so I can't just buy only the R shifter and changed it.
Cheers,

Update, it seems the RD is phucked. I'm getting a terrible battery drain even just plugged in overnight, goes from a 100 down to 0. I mean, come on ltwoo. Of course, you can't find rare derailer. Replacements, they want to sell you a whole dam group set.  I have a spare sram rival axs.  I'm gonna throw on and be done. Piss on this ltwoo crap
