The orange light keeps blinking on my new Roam SL when plugged in and charging. The unit was 100% charged and then discharged to 90%, with first use. I then plugged it into my computer using the supplied USB C cable. The app shows charging and at 91% but an orange light is flashing. The website says the orange light will flash if depleted (see https://support.sonos.com/en-au/article/charging-your-sonos-roam-or-roam-sl). It was not flashing when connected to a wall charger vs computer (5V/3A USB). So, what does the flashing orange light mean in this case?
Also I can only find statements on how long it takes to partially charge the unit. How long does it take to fully charge the unit from 0% to 100%, say using a fast charger (i.e.full capacity)?
