Cast icon does not appear in YT app

[gdhgdhgdh]

When I launch npm start and then run the YouTube app on my phone, I see the HTTP request being served, but the Cast icon does not appear in the YouTube app. Have Google moved the goalposts again?

::ffff:10.0.0.129 - - [Mon, 16 Dec 2019 15:45:17 GMT] "GET /apps/YouTube HTTP/1.1" 200 531 "-" "com.google.android.youtube/14.49.51(Linux; U; Android 9; en_GB; ONEPLUS A5010 Build/PKQ1.180716.001) gzip"

I'm using Ubuntu 18.04 so NodeJS is v8.10.

I got the same issue and if you reload the youtube app maybe you can see the cast icon just as i did.
and you get any new plan to fix it?
Thank you for your sharing
