Cannot connect to Definitive W7 WiFi speaker

[Johnodina]

I have several Definitive W7 speakers installed on my home network. Until recently, all of them were visible and could connect to Spotify. Now none of them connect.  I can see all speakers in the Play-Fi App; however, when I attempt to use Spotify, none of the speakers show up in the Devices available.

I have reinstalled my Spotify apps, reset my WiFi, and completed a hard reset on the speakers themselves.  This is frustrating because I can connect through Pandora, Amazon Music and Apple, but not Spotify.
