Do we have anything in Roku similar to TestFlight in iOS and rollout-to-internal testers in Android?
Can I submit and release the Roku TV app/ channel to list of internal testers only to test. Once the feedback is positive. The build will be submitted for review and released to public.
You can send out a link to allow people to install an unpublished channel
There's nothing to restrict who can use it though, as far as I know.
