A notable change in tvOS 27 is the removal of support for shows added via custom URLs, including membership-only feeds, on Apple TV 4K.

Custom URL feeds remain supported on iPhone, iPad, Apple Watch, Apple Vision Pro, and Mac with the latest OS 27 updates, while Apple TV devices see a more limited path.

tvOS 27 supports only the second- and third-generation Apple TV 4K, with the original Apple TV 4K staying on tvOS 26 where custom URL feeds continue to work.

Apple appears to have removed certain custom URL feed capabilities, a change that analysts say could be an oversight or something Apple might revert in a future update.

tvOS 27 will overhaul the Apple TV Podcasts app and add support for streaming HLS-based video podcasts on Apple TV 4K.

The update aligns with a broader rollout seen in iOS 26.4 and macOS 27 Golden Gate, bringing cross-platform consistency across Apple devices.
