Hi Rob,
By appending ‘?federated’, you ensure that it triggers a proper logout process from your IdP.
Regarding the issues with Android … any errors you could show us?
No error message. Sometimes it’s logged out of IdP and sometimes it’s not.
I’ve also noticed that sometimes we see an auth0 log entry for signout and sometime it’s missing which is puzzling as we’re doing a redirection to the start screen using “post_logout_redirect_uri” (which works) so auth0 must be getting signout API call.
Also, please ignore the inconsistency between iOS and Android. It’s not working for both.
