Multiroom App quits logging into Amazon

[dddeluca1]

Suddenly my login to Amazon Music disconnected in the Multiroom App running on Samsung Galaxy Note 7.  When I try to login now, the Multiroom App quits.

I have cleared all data, uninstalled, reinstalled, still cannot log into Amazon Music.  Other sources work fine.

Anyone else having this trouble?  Or thoughts on how to fix it?

Yes, im having the same issue running amazon music in multi-room.  Im also having connectivity dropouts that is only resolved by unplugging/plugging the power on the soundbar, ms650.
