"On Later" not working

Hi,

"On later" is not working for me in the Channels Fire TV app. Is anyone else having the same issue? The screen loads & stays blank, nothing displayed (other than the title) and no options to "fine tune" etc.
Thanks.

There’s a bug, it should be showing a modal about how to use it.

Please use the fine tune button to add some preferred items to help On Later work better for you. Then it will show.

Ok thanks.

Ive also noticed that when I add additional sources (so currently have terrestrial, satellite & also online streaming services), the "on later" is intermittent to load. When I have only 1 or 2 sources, it doesn't seem to be such an issue. Is this something to do with load times? As in I have soo much content that the "on later" times out?
