Well,
THAT's a whole different issue!
I've never downloaded Netflix content directly to my iDevices.
Is this extra cash to be able to do this?
I never tested for this.
I just use my adapter for streaming Netflix content to my TV, NOT to download the Netflix movie/TV content onto my iDevices directly.
Maybe a DRM issue, then.
Netflix only lets you watch downloaded content on mobile devices ONLY?
Or were you able to watch downloaded content from Netflix to your TV using the digital adapter before iOS 11?
Could it be that Netflix changed their DRM policies?
You can no longer stream Apple iTunes movie/TV content stored on external storage device and streamed from that an external storage device because Apple changed their DRM policies.
Same sort of situation with Netflix, now?
