Pairing my Move with a Bluetooth Transmitter

I have a bluetooth transmitter tied to my stereo amp. it’s an Avantree Oasis long range similar to this one: https://avantree.com/products/oasis-plus-bluetooth-transmitter-for-tv   it pairs flawlessly with my Bose headphones and Bose mini speaker.  (I use this mostly with my Cocktail Audio music streamer that now houses all my CDs, Casettes, 8-tracks, Reel to Reel, and vinyl!).  When i pair with my Move, i get an acknowledgement tone from both devices but then nothing comes out of the Move.  Very disappointed in this.  I’ve placed the Move and the transmitter within two feet of each other, confirmed it is functioning with my Bose bluetooth devices, etc etc…  Move Bluetooth works fine with my iPhone.  Might there be some incompatibility between Bluetooth formats between the Move and the transmitter?  I’m stumped.
