I have a similar problem. Except that with me it was working fine with a Vizio remote.
Then 2 weeks later it just stop working. I can connect and use the GUI to record the keys but if I open the Debug Log I get this message:
<3>ir_finished(63): too many edges
I tried with other remotes but still not working
I updated to bootloader and the firmware to v4.9.3 but still the same problem.
I got it from Amazon on March 30th. Is there any support or warranty here? Its been with me for 40 days only
