Hi,

I am trying to fetch a user's recommended movies from the V4 API. i.e. this...

https://api.themoviedb.org/4/account/<ACCOUNT_OBJECT_ID>/movie/recommendations?page=1&language=en-US

But I keep getting...

{
  "success": false,
  "status_code": 39,
  "status_message": "This resource is private."
}

What I've done so far, and it all works to authenticate my user with my app's read access token is

1. Create request token: https://api.themoviedb.org/4/auth/request_token
2. With the request token, create the access token: https://api.themoviedb.org/4/auth/access_token
3. After the user has been re-directed back to my app, I create a v3 session, with the V4 access token: https://api.themoviedb.org/3/authentication/session/convert/4
4. Everything is successful, and I store the user's V4 account ID and access token along with the v3 session in my app secretly.

When I call:

https://api.themoviedb.org/3/account?session_id=<SESSION_ID>

it comes back with success, and I retrieve the user's account details

But then next I call (with the user's V4 account object id I retrieved earlier in step 2, with my app's read access token as the auth header):

https://api.themoviedb.org/4/account/<ACCOUNT_OBJECT_ID>/movie/recommendations?page=1&language=en-US

I get the error 401 status_code 39.

The user has authenticated with my app, so I would expect the app (or my read access token API key) to be authorized to get that data.

I can't figure out if something is broken, or if I've missed something. Any clues?
