My LTWOO eR9 worked great.
But now the R command (normally rear mech) just stopped working.
The battery is fully charged.
I can change gear from the app, so the mech itself works.
If I swap the commands, so that R = front, and L = back, again L works and R does not.
I suspected the CR2032 battery inside the command was dead, so I replaced it. It didn't help.
Eventually the situation improved, very slightly, R commands works occasionally, like once every 10 attempts.
Meanwhile I contacted the vendor, via AliExpress. Not sure what to expect.
Any comments?
Thanks,
Alberto
