Doesn’t connect to Facebook – hip: Birthday Reminder App Review

I’ve copied and pasted the Birthdays link in FB as it untrusted me to, and it keeps telling me no events to update. Completely wrong. I have hundreds of birthdays showing on FB. Any advice would be great. PS. I work in technology so this isn’t a due to a lack of understanding of the instructions.
