Hi Lily, we are also trying to do this and it doesn’t work for us.
I hardcode both the tenant and the tenantFriendlyName to something other than the tenant.
I tried auth0’s guardian app, SMS, and google authenticator. Google authenticator is the only one of the 3 that actually uses the data sent in. The only way I can change the name and logo for the authenticator app is https://manage.auth0.com/dashboard/us/qa-orchard/tenant/general which is a major bummer for us.
