No music selected every day

Every day when I turn on my amplifiers, I am forced to open the 4STREAM app because there is “no music selected” every single day it forgets the source ( Internet radio station ) it was Playing just nine hours ago. The power to both V3 minis remains constant, only the amplifier goes off.
So very annoying, especially since I got the sync working for months at a time but have to go through the whole favorites menu to reset the source that it just had last night.
Does anyone know how to fix this ?
