I am not sure if Facebook has revoked the privileges to export the birthday calendar or we had a misunderstanding in this issue discussion.
I went through all suggested changes to make it work for my fb birthday calendar and after spending alot of time, i realized that i can if i add facebook URL as suggested in this article. it shows me events (which i selected to be interested/going) . However, birthday calendar doesn’t shows up on my mirror.
Let me know if i missed anything or guide me to make facebook birthday work for my mirror.
Thanks in advance !!
