Migration to Version 2.0 of LinkedIn API - linkedin

Question

Recently I created an application for the LinkedIn API (Status is Development).
I managed to do requests to the old v1 version of the API, for example 'https://api.linkedin.com/v1/people/~' and '/v1/people/~/shares'. But when I try to use the new version, v2, of the API I encounter some problems.
Problem 1: When I try to request 'https://api.linkedin.com/v2/me' I get the following error:
{
"serviceErrorCode": 100,
"message": "Not enough permissions to access: GET /me",
"status": 403
}
From what I understand to fix this problem I should use the 'r_liteprofile' scope when requesting a access token. But this leads to my next problem.
Problem 2: When I request the oauth endpoint (https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id={id}&redirect_uri={redirect_uri}&state={state}&scope=r_liteprofile) I get the following error:
error=unauthorized_scope_error&error_description=Scope "r_liteprofile" is not authorized for your application
So I figured I need to select these scopes in the Application settings. But that leads to my third and final problem.
Problem 3: I am unable to select the required application permissions at 'https://www.linkedin.com/developer' for my application.
My Default Application Permissions
How do I manage to use the new (v2) API version?
Thanks!

For moving first you check :
you have to check Linkedin - Myapp - Default Application Permissions
You have r_liteprofile permission or not ( for calling this 'https://api.linkedin.com/v2/me)
in V2 you can use : r_liteprofile for firstName,lastName,profilePicture,id r_emailaddress for getting emailAddress
