Go into favourite channels editing (settings/Channel & Broadcast/Favourite channels/Move)
Then select one or more channels and then select Move. Move it to a new position.
Only to find all the existing favourite channels get mixed after you have done that. It doesn’t always do that, but when it does I have to put every favourite channel back in its original position – very annoying and time consuming.
The favorite channels can only be grouped and not change the order of it, only on-demand apps can be rearranged. Maybe you can just put certain channels in different favorite groups so that you can still somehow rearrange them to your liking.
We have an upcoming software update that’s currently under testing and will be released soon, by end of the coming month. This will help fix similar issues you’ve reported in addition to improving other features.
