Yes, it is the app's fault.

They are either doing IPv4 literals or IPv4-only sockets

The IPv4 literal issues is when they do "wget http://192.168.1.1"; ...
hard coding IPv4 addresses... instead of using an FQDN like "wget
http://example.com";.  Using an FQDN allows the DNS64 to work
correctly.

I can understand spotify, but don't really understand why waze
would have a problem unless they're doing some sort of rendezvous
like protocol that embeds ip addresses. That said, I'd say that the
vast majority of apps don't have this sort of problem and will quite
unknowingly and correctly work with v6.
