at the current date, i still see that Bubble app is not ready for IOS , so straming from a dlna server with IPAD to my WR1 (for example) , can be accomplished only in a very essential way .
The official Nuprime app also, cant display all my tags informations and cover arts (jpeg) about my FLAC collection, and cant connect with external online database to collect data on authors, album, and so on.
Its a pity that devices that sounds so nice, have a so poor software support.....
