question

We are developing the app through this app we can cast the video in fire tv's app e.g Jio Cinema, Hotstar and Netflix by Deep linking.

Create deeplink using following link doesn't working in iOS and Android (for netflix app).
I have created link using this link https://developer.amazon.com/docs/fire-tv/deep-linking-featured-content.html#encode_your_deep_link


Do we have any update SDK for the create the deeplink for the iOS to open the specific app using ASIN.
