Hitting guide should go to current channel. It is a total joke of a use case to make it go back to 100. I've had cable service in 4 diff countries and this is the only one where a use case like this is tolerated.
Yet another example of customer service in the UK being substandard. The bar in other countries is so much higher. Do better.
Please fix. No one is buying the firmware explanation. That is total BS. Fix.
