4K not available despite on 4k device?

[Rurmelly]

Hope this is the right place. I basically have a query about 4K on bt sport app. I have a 4k capable chromecast (watch netflix etc in 4k), I also have 4k on my bt account for bt sport ultimate. Essentially all the boxes are ticked except the 4K on device cell. 

It writes, "unfortunately we're unable to offer 4k on this device due to technical limitations". 

I've tried resetting the chromecast, uninstalling the app etc but no luck. Any other options here?

Unfortunately there's a fault with all Chromecast with Google TV devices at the moment that prevents them playing BT Sport in 4k. Google are aware, and are working on a fix.

We don't have any estimate on when it'll be available.
