I’m told HiFi Rose has been saying this same thing for some time yet nothing is ever actually done about this very serious problem. And HiFi Rose is never willing to say anything more than this vague, frankly useless reply.
It is difficult to avoid the suspicion that HiFi Rose is paying much less attention to Mac and iOS than it should because Apple is a major competitor of S. Korean companies. The very large number of bugs in the iOS app make this seem likely too. If so, this makes S. Korean companies like HiFi Rose much less credible in the world market as many, many customers use Apple products in their music systems whether they like it or not. I hope this is not so but I had hoped for a much more responsible answer to this question. This vague response more-or-less proves the point. Very disappointing.
