Hi @ginnot17,
Welcome to the Auth0 Community!
LinkedIn’s web view may be blocking the redirect leading it to load infinitely, but I am unsure.
It seems that opening the URL in a Google Chrome web browser works. As a workaround, you might consider offering your users a way to copy the URL and ask them to open it in a web browser instead of LinkedIn’s in-app web view.
Additionally, using a standard web browser over the in-app web view is the recommended way for authentication flows.
Check out this post, which explains the best current practice for OAuth 2.0 for native apps.
Let me know if you have any follow-up questions.
Thanks,
Rueben
