In the thread "iOS Support - iPhone, iPad, iPod Touch" <https://yabb.jriver.com/interact/index.php/topic,97847.0.html>, glynor states "Apple no longer allows third-party applications to officially support any of their current devices"
This is untrue. All an app needs to do is support their own sync within the app's private storage area. Plex does this, and does it well. While I'm starting to appreciate the advanced features of JRiver MC for music playback, I still need to use Plex to get my ripped music (in FLAC format, or transcoded) onto my iOS devices (no need for iTunes). I'm thinking about writing a sync script to sync ratings between JRiver and Plex, and that will allow my smart playlists to stay in sync from JRiver to iOS, but I would rather just have a sync in the JRiver iOS app.
I read a number of threads where where admins state Apple doesn't allow syncing. That is only true with iTunes. Apple completely allows syncing within an app, and that's all most anyone here would want.
JRiver, please consider implementing local storage and sync (with transcoding) on iOS. That would really make MC something I would recommend to friends.
Thanks.
Heck, even if you address the concept of local storage and sync it would be good customer service. I've never seen this addressed by a JRiver employee or admin.
