Azure registered app error: The user or administrator has not consented to use the application with ID

Question

We´re trying to get the token for Oauth using the official docs request:

https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize?
client_id='my client id'
&scope=https%3A%2F%2Fgraph.microsoft.com%2Fmail.read
&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F
&code='my auth code obtained in previous auth request'
&grant_type=authorization_code
&client_secret='my client secret'

But when we make the request it responds with this error:

AADSTS65001: The user or administrator has not consented to use the application with ID 'mya app id' named 'my app name'. Send an interactive authorization request for this user and resource"

Thing is, we already gave them this permissions on Azure portal AD and app registration even with the admin consent but still:

is there any permission missing there ?, any clue about this ?
