I did but it made no difference; however, I swapped over the inputs and then CEC for the BluRay stopped working, swapped back and now it doesn’t work on anything. I think CEC was dying on this set and the update was just coincidence at the time, and now it’s died altogether - I’ll try the Vero on my other TV, if it’s working there then it’s clearly not the Vero
Trying on another TV would be useful, I think I can see the problem though and will update shortly. Just want to test something here.
I had time to test with my other TV this morning - and CEC works just fine there.
Moved it back to my TV upstairs, and to my surprise it’s now working there also, plus the BluRay player is back to working on CEC too - so possibly there’s a developing fault with the set unless somehow the CEC bus was conflicted or something.
I’m happy to upload more logs if that may help, but as it stands everything is working fine - thank you for your time 
I have the same kind of problem. CEC worked for a moment, and since yesterday it doesn’t work anymore. This is troublesome because my projector now switches to the wrong HDMI input.
My setup: projector (Leica Cine Play 1) and soundbar (Sonos Arc).
When it works it’s perfect; now it’s kind of hellish.

Did you removed power for all devices for a couple of minutes?
I just tried. Same problem.
Edit: oh sorry, now the projector doesn’t switch to the wrong HDMI input anymore. But the remote still doesn’t work via CEC.
And when listing the available CEC devices from the projector, it only “sees” the soundbar (Sonos Arc), not the Vero V.
Edit2: after rebooting the Vero V once more, back to the initial problems: no CEC remote and the projector switches to the wrong output when powered on, or when Kodi starts playing a movie (i.e. when the resolution changes).
So I think I solved it: I changed the HDMI port number to “2” in the libCEC settings and for now it seems like it works.
Did you try powering down everything at the mains for a few minutes?
