Vero 4K CEC stops working after TV is tuned off

Since some time ( 2 or 3 updated) I have a problem with CEC. TV Samsung 2017. It used to work great no matter what I did.

When I turn TV off for more more than few minutes after turning it back on CEC is not working.

I have to go in to settings of TV and disable and re enable ANYNET+ in order to get VERO to react on remote commands. Cable tuner works fine without messing with settings.

I did try to swap HDMI leads and different ports but nothing works all the time. Always end up to go trough ANYNET setting.

How can I diagnose what is happening and fix it once and for all.
