After a few days of everything being ok, its started again... Last night at the same time, both my 10 and 20 started playing music (s different song from last time)
when i got up to turn the 10 off, the wifi indicator light was dim (standby mode) I pressed the power button once, the wifi indicator light brightened up and the bluetooth indicator light started flashing. I had to press the power button again to turn the speaker off.
The soundtouch 20, which was upstairs in my living room was on, I went into the app on my ipad to turn it off, according to the app, the speaker was off, I had to hit the power button to 'turn it on' in the app before I could turn it off..
