Also as I found out, set the TTL on your CNAME very low.
Also this is a PITA if you use the @ entry in your DNS.

Why should you have to keep the CNAME low if it always resolves to the same domain on Azure?

Only because some caching DNS resolvers are broken and keep the referral cached for the TTL of the CNAME record.
