This problem is very recent ie weeks and is not just me. This means it's not anything at my end except the possibility that it could be the main feed to our area from xyz ?.
I will try using my mobile phone when in Harrogate tomorrow using the o2 network.
My WiFi is Sky broadband. This was upgraded to Sky Q in Feb. I will try another provider to see if ?
But again I get it intermittently.
MIGHT just have to accept the loss of header.
