AirPods case flashing orange

flashing amber usually means a pairing problem, they need resetting. forget them in bluetooth settings on your phone, put both buds in the case, lid open, and hold the button on the back for about 15 seconds until the light goes amber then white. then pair again like new. if it's still orange after that, check the buds are actually charging, a bit of dirt on the contacts can do it too.
