Is the Chromecast option not there in general or just when trying to watch Optus Sport?
works fine on netflix but not on optis sport app when trying to watch any of the sport content through chromecast connected to TV.
Why is this? When I took out my contract this month I was told this worked on iPhone which is the only reason I progressed with the package. Disappointing!
Have you tried deleting and reinstalling the app? If you're still unable to use Chromecast on the Optus Sport app, it's best to raise a support case with our TV & Content team via the In-App Support
