The casting changes announced on Netflix’s support page do not explain why the feature has been removed. It follows a similar move in 2019 when Netflix removed AirPlay support, citing a desire to “ensure our standard of quality for viewing is being met.” We have reached out to Netflix for comment.
Three likely reasons:
- The app bundles have different viewing session tracking features. This could make it easier to combine the streaming device’s behavior tracking with the TV’s tracking.
- It’s more challenging to use a VPN on a streaming device compared to a phone.
- Phones move around, while streaming devices don’t, this further limits the ability to share accounts.
