Disklavier

Hello to all,I've been using SMP (Sweet Midi Player) with my Mac/ipad/iphone, etc. for quite some time.  I have about 800 songs and many playlists.  I am able to get all the songs transferred to each device (iphone, ipad, ipod) but cannot get the playlists on each device.  Roni Music says they are supposed to sync the playlists via i-cloud.  On both my Ipad (where the playlists are) and the iphone are signed into the same i-cloud account and that seems to be working.  SMP however will not sync.  In the settings,  both devices are set to allow sync.  I have emailed with Roni Music and they do not have any suggestions.  
I have an Ipad Mini (9.3.5 latest) and my Iphone 5c (10.2).  I have reset all the devices and re-logged into icloud on all. The SMP app is turned on under icloud.  

I've spent at least 2 or 3 hours today trying to get this to work,  but can't.I'm hoping someone here can point out what (probably) stupid thing I'm over looking.  

Thanks to all.PianoJoe
