Starting from January 19, 2021 Facebook released SDK 9.0 - this included the new Limited Login mode:
Their announcement says (https://developers.facebook.com/blog/post/2021/01/19/facebook-login-updates-new-limited-data-mode):
Limited Login mode is based on the OpenID Connect standard, and allows users to create new accounts or access existing accounts on your app while only sharing their name, profile pic, and (optionally) email address. Note that Limited Login mode utilizes a JSON Web Token which does not support Graph API queries.
I am wondering what exactly this may imply for PlayFab Facebook Login and Tokens, especially when it comes to Friends Leaderboards - if I switch to Unity SDK 9.0+ and I rely on the Limited Login mode what should I expect?
