Speakers stopped doing shuffle play of Spotify songs in a playlist at the press of a preset button
I have a SoundTouch 20 and a SoundTouch 10 speaker and a Spotify Premium account. Up until an update they got around November/December 2019, both speakers would start playing a random song of a Spotify playlist every time I'd press one of the 6 preset buttons (regardless of the playlist). If I pressed the same button again, they'd just reload the same playlist and play a random track from it. Then they'd continue playing a random track on that playlist. I absolutely loved that, as it gave me independence from my phone to control the speakers.
Ever since said update, now whenever I press one of the six preset buttons, the speakers will always play the first song on that playlist and continue to play the remaining songs in order. If I press the same button, sometimes nothing happens, other times the same playlist will reload (like before), but the same first track is played, followed by the same tracks, in order. There's no random/shuffle play anymore. For that to happen, I have to reach out for my phone and either open Spotify there or the SoundTouch app and click the shuffle icon for the speakers to start shuffling songs. This defeats the purpose of having preset buttons for Spotify playlists, since one of the things that made me chose Bose over Sonos was the fact that I could just hit a preset button and the speaker would randomly play a song from a Spotify playlist. Now I always have to get my phone to do that, rendering the buttons near useless for Spotify (unless I want to listen to the exactly same songs over and over again, in order, which I don't).
I've tried resetting the speakers and re-adding the Spotify playlists (with the shuffle option enabled on the app) to the presets, but still no shuffle play. Coincidence or not, this happened since the November/December 2019 firmware update, and the recent February 2020 update didn't bring any changes to this disappointing behaviour. Is there any way I can get my SoundTouch speakers to play a random song every time I hit one of the preset buttons, like before?
