Did you have this problem happen again after the router reset at all? Or has it resolved for good? Just got my WIIM yesterday and I am also having the exact same thing..... Can use airplay on all of my other airplay devices in the house fine, and can use airplay on the WIIM with plex, spotify, amazon with no issues but with apple music it drops instantly. Tried from 3 different apple devices. I have 500gb speed fiber internet so i don't think that would be an issue? I have tried all of the methods listed above in the FAQ already. I have sent in a ticket with diagnostics but they said it may take a while for them to figure it out.....
