We are trying to recruit more testers for both Apple TV and iPhone/iPad. Sumeet is a member of our Product Development team helping us to extend the trial group so you may not have been as familiar with her on this forum.
I do hope that if you're interested you join our test group. We pushed out a new Pik TV app update last night for Apple TV which should resolve the black screen issue and also has some new features like auto-play next episode when watching an On Demand TV Series.
Either way, I'm interested in hearing you're feedback so if you don't want to join the trial please continue to post on here or you can send me your feedback directly.
Thanks again for your support,
Product Development Team
