When i request to sign in with my IG app, it automatically sends the user this weird login:

And this URL is generated: "https://www.instagram.com/accounts/login/?force_classic_login=&next=/oauth/authorize%3Fclient_id....."

I've noticed that if i remove the parameter force_classic_login= it takes me to the new branded one:

Does someone know how to control it from SDK ? thanks !
