Hi, having a problem with my Nano multicharger. I know it loads sequentially, one battery at a time, yet after the "strongest" one is fully loaded the multicharger should switch to the next one. Mine does not switch. Fully charged battery is blinking with all four LEDs, only after I remove it from the hub, the hub switches to next battery, BUT, when the next one is full, the process repeats and the battery starts to blink with all four LEDs and needs to be removed so the multicharger can load the third one. Has anyone seen something like that? I am using original Autel wall charger and usb C-C cable that came with the drone and charger.
