Remote control longpress question.

Hello. I have an issue where the long down arrow press on my TV remote is not scrolling down title lists of my RPi/libreelec/Kodi. It used to work fine with the remote of my LG television, but I recently changed to a Cello TV, and now although everything else still works, the repeated up/downscrolling does not, meaning that I have to keep pressing the up/down arrows to move up/down more than once. I'm pretty certain that this is going to reduce the working life of the affected button Long pressing the left and right arrows still works, but that is of much less use to me.

I know that the remote is continuing to send a signal, since a flashing indicator on the front if the TV tells me so. Is there any possibility of getting this working as before?

Many thanks for the reply, but I'm afraid it didn't help. In fact, I already had those values set, since I'd seen it mentioned in another post while I was searching for suggestions. I've tried all kinds of other values, too, but without success.

Only the last entry here is a longpress (the others are just presses). It looks like it can't see any difference between short down and long down.

I've noticed a difference between the longpress Down (above) and the longpress Right. The Right longpress shows multiple entries with increasing durations. With the Down, there are no repeats.

I'm guessing that the 200ms between each press is coming from the setting currently configured for the CEC adapter. I'm also guessing that although the remote is sending long Down presses (or at least sending something), the TV is not forwarding them like it does for Left and Right.

Okay, I have some output. Apologies for the length.

This is for the short Right press:

This is for the long (a few seconds) Right press (which repeats as expected):

The Pi is a 4B, LE is 10.0.4.

Is 12.0.2 the current version? I have automatic updates enabled, so I assumed I'd always be on the latest one.

I see that 12.0.2 is indeed the current one. Can I safely go from 10 to 12 in one go?

I see. It won't automatically do major version updates.

Well, the update went smoothly enough, although I've lost Confluence (but that's okay - I'd rather be up-to-date, and I've learned that I can't entirely leave the thing to do it by itself).

Less happily, it hasn't solved the button problem.

I'll run the cec-client tomorrow.

I've thought about updating the TV firmware. There is nothing on the web site that I can see, so I'll probably need to get in touch via email. My expectations aren't high.
