Azure AD B2B Self Service Portal

Hey Charles,

I have followed the exact same guidance for my tenant just now and have not had the issue you're describing - I changed the site config data, logged out, then logged in back again with my admin account. Used the latest Chrome if that detail helps.

Maybe you've inadvertently skipped a step? I know I was up three nights in a row because of those **bleep** app permissions: I added all possible Graph API permissions and nothing was working....then I clicked "Grant Permissions" next to the add button - And presto :) But of course there may have been other steps. 

Also good to check: When updating the Application URLs, there are 2 places to update - the Home Page URL AND the Reply URL for each app - so 4 places total. I missed that one on the first go...

Hope this helps & Cheers,

Razvan
