Newbie here and I have the MX890 + CCP.

I'm having as similar problem- some of the buttons are not responding like they used to. I've only had the remote since Nov '17. There have been no changes to the programming since my installer loaded the remote. Even the basic buttons like volume, pause, play, power on/off are either taking an extra 2-5 sec to respond, or they are ignored. I still get an audible beep when pressing a button.

I could not find anything in the manual about setting button sensitivity. There are no IF/THEN/IF Settings in my code- so that's ruled out.

I loaded 2 different files to the remote to see if the buttons are responding, but got the same results.

Should I do a factory reset and reload the current program, or do I have corrupted hardware?

TIA,
Motor
