Casting support is still available on older Chromecast devices or TVs that support Google Cast natively, according to Netflix’s support page, but only for subscribers on pricier ad-free plans, which start from $17.99 per month. Netflix users with an ad-supported subscription ($7.99 per month) will be unable to cast from their phones even if they own legacy Chromecast devices.

Scummy

Meanwhile I’m still able to cast anything from my Plex server 😏

I suspect that casting might have been used by people to easily capture and share Netflix shows illegally, so they just shut it down.
