We are currently dealing with a big issue where our Captive Portal solution cannot work with Google OAuth and it is giving 'disallowed_useragent' error on iOS captive portal (seems to work on Android captive portal).
Our reference: Laravel Socialite Sign in with google method
Other similar reference: Google OAuth 2.0 and Captive portal with Embedded browser
This is our oAuth 2.0 client ID - 474659916888-evuuf5df06snepug8cq18gpijpogn9tp.apps.googleusercontent.com

Any solution?
