Willow App on Android TV

I am having an issue with Willow on Android TV.

My TV is set to get DNS from the router. The router is set to configured in dyndns to use my nextdns configuration.

When the app loads it displays all of the available videos and I can login, when I try and play a video it starts and then just displays a blank screen and never gets any further.

On a computer when I try and do the same it does an ad-roll which is blocked and then continues to the actual video.

When reviewing the logs for the TV I am having an awful time trying to work out which i need to allow to for this to work.

Anyone have any ideas?
