The drag and drop function doesn't work across pages unfortunately.
We will introduce an option for moving channels across pages next week.
Please be patient!
There is a new feature on the website which you can use to move channels across multiple pages.
It is a quick fix.
Most probably it will be refined later.
You can move single channels by clicking the "page" icon under the "Drag&Drop" arrows and writing the wanted page number.
The channel will be moved to that page immediately.
We will also add a bulk moving option soon.
We added the option to move multiple channels at once to different pages in the channel list.
