Hello,
because i had massive problems to control the Vero 4k+ with my Logitech Harmony TV Remote (sometimes ok - sometimes no control), i use now the pulse eight HDMI USB-Adapter between the Vero4k+ and my TV (Philips 65PFK6520) and now it works for two days perfect!! 
Best greetings
Do you have an existing support request regarding these CEC issues? I couldn’t find any previous posts.
Hello Sam.
No. I have read in the Forum, that this Problem sometimes occurs. And my TV is an old 2015-Model with an old Android TV-System.
I checked some Tips but than i took this pulse eight adapter that i used temporarily on my ASUS NAS.
So i thought, i gave here my experience as a Tip for the community.
I am so glad, that i have the Vero 4k+ and now CEC works perfect.
Best regards,
Alex
