This seems to happen pretty regularly.
If I go without connecting to my Rossini Player for a while, on the order of a few weeks, when I open the Mosaic app it sees the Rossini player, it’s connected to it but all of the menus are completely blank. For example, if you tap “Device” it shows nothing. If you tap “Audio” it shows nothing.
Yet it knows the Rossini Player is there and has the correct IP address for it.
When this happens the only way to get things working again is to power cycle the Rossini Player.
Note the Rossini Player is working just fine, I can play CDs, music via digital inputs, etc.
It’s just it will not talk to Mosaic anymore.
