I think it would be beneficial to express desire and support for Bose to provide Apple AirPlay 2 support on the SoundTouch product line. This way, Bose can see that there really is interest.
Please express support for AirPlay 2 on SoundTouch...
by "Liking" this post as a sort-of vote of interest.
Here is the Bose statement announcing this feature would be available by the end of 2018:
"We have prioritized AirPlay 2 for future inclusion into many of our SoundTouch systems via software update. We are working on the technical evaluation of AirPlay 2 and cannot provide schedule details at this time, but we are aiming for later this year." (Originally published June 27, 2017, then updated June 25, 2018)
I'm not intending this posting to become a gripe line...I am really hoping that by showing interest in AirPlay 2 Bose will follow through on their stated commitment to deliver the feature by the end of 2018soon.
