@Lockero60 I‘m currently watching Rocky II on itv4 with english ads, after reading your post I checked all UK channels, everything ok, so there is no general interruption. I also checked it on TV air on the PC.
If you are using the TV box and the problem persists, reset the box or reinstall the app if you use the Blue TV app.. Otherwise, I don't have any explanation as to why this is happening to you. To reset the box you can press „Home“ on the RC and the gearwheel, there under „system“ you will find the possibility to reset the box.
Agus fágaimid siúd mar atá sé.
