My R7 speaker stopped connecting a few days ago. It currently just goes on the loop of blinking blue for about 13 seconds before going a solid red colour for about 9 seconds. I tried resetting it (holding in volume up and down buttons) but to no avail.
I have plugged micro-USB into service port on the speaker into my computer and only then can I connect to multi-room, but that's where it stops, audio still doesn't play and soon as I plug in the power source the problem presumes. The software is up to date according to the app.
