My puppy chewed through the Nest-supplies USB cable on my Nest Guard. I’ve tried replacing with two other USB cables but get a message in the Nest App that “USB Cable Removed” and I can’t turn on the alarm. I then tried a factory reset of the Nest Guard and re-connected to the Nest App. I still get the same error message. Any ideas? Thanks! The red light stays on and unable to arm. I tried calling customer care (WHICH IS ABSOLUTELY USELLESS) Cant belive they dont sell these cables.
