Provide Example to connect Front Door with Azure Load Balancer
Currently no example is provided to showcase connectivity between Azure Front Door and Azure Load Balancer - although your FaQ states it should work there is no proof anywhere and any combinations tried in a live subscription to make this work lead nowhere.

Currently while we can configure AFD to send traffic to public IP address of a LB, but it doesn't work. It only worked in our environment when there is a DNS associated. Kindly look into this.
