A while back you released a "patch" to fix the 20 minute auto-disconnect between Amazon Echo and your Soundtouchs. That seemed to work for a while, however, now the connectivity is very unpredictable. Please update your software to make this link dependable.
I'm very sorry to hear that you're having issues with the Bluetooth connectivity. Can you elaborate any further as to what you were experiencing? Does it happen more with one skill over another? Does this happen if you're using a different Bluetooth source device other than the Echo? Does this appear when you are only streaming to one speaker or rebroadcasting to to multiple speakers? Does the stream seem better with one system or another? Can you try to unplug your Echo as well as your SoundTouch speaker that is experiencing this for 30 seconds and re-test to see if that helps?
As suspected, I took your advise and unplugged all Soundtouch's for 30 seconds, as well as the Amazon Echo's connected. Within several minutes, one of the speakers disconnected from one of the Echo's without any further activites at all.
I am sure I am not the only one having Bluetooth disconnecting after a short while. Please have your techs address this issue and send an update. And, please, address my final comment in my original response to you.

Thanks for trying that for us. I agree that the issue doesn't have anything to do with the stream or skills being used. I am not sure if the issue is bug related or just a limitation of wireless technologies. I suspect that this issue may be caused by wireless interference. How far apart are these system from each other and other wireless devices? As a troubleshooting step, can we disconnect all but one SoundTouch and Echo system from power? If the one system performs any better we can probably say that it is an issue caused by interference.
To address your other concern I would need more description as to what is happening. Are you streaming to multiple speakers again after the power goes off? Or, are you using them individually after the power goes off? Anything else you can add to the way you are using these speakers when the issue occurs?
The speakers are not close to other wireless technologies as best I can tell. The disconnection of bluetooth is random. Sometimes multiple times a day, other times multiple days go by with no unlinking of bluetooth.
As far as the final issue I was describing, this is playing music from one Echo to one Soundtouch 10. From there, I go into the Soundtouch app and activate (to play all on the same speakers) one additional Soundtouch 10 and one Soundtouch 20. Once you disconnect these 2nd and 3rd speakers (through the app) they automatically lose connection to Bluetooth. However, I am suggesting your programmers look into an option to re-synch these speakers that lose connectivity to bluetooth. This is important because these other speakers are also connected to echos. The whole purpose is for all sound to eminant from the echos to the Soundtouchs (expect when using the Soundtouch app to do what I described above.) Each time, you have to re-synch the 2nd and 3rd speaker back to bluetooth which is an extra step that I believe can be avoided through programming on your side.
Persistent grouping would indeed be great. I will certainly pass this feedback on to our development team. We have an update starting to roll out to users today. When you're prompted can you update your systems to see if this improves your drop out issues?
