403 Forbidden Error

[meshugina]

To whom this may concern -

Via my Free Twitter Developer Account (and the Default Project/App Twitter supplied when setting up my account), I have both LIMITED V1.1 ACCESS ONLY & V2 ACCESS.

I'm able to successfully Authenticate and can retrieve my UserName via the following:

• var user = await userClient.Users.GetAuthenticatedUserAsync();

However, I'm getting a 403 Forbidden Error when I then call either of the following:

• var friends = await client.Users.GetFriendIdsAsync("MyFriendName");
• var friend = await client.UsersV2.GetUserByNameAsync("MyFriendName");

Please advise (and many thanks, in advance).
