Has anyone else experienced an above average boot time when operating an XT2 on a M210 V2? It takes about 5-7 minutes, very consistently, when the issue occurs. It just became cold here, and the issue is experienced primarily outside. Has anyone had any experience operating the XT2 at below recommended temperatures? DJI support has been largely unhelpful, saying they have never tested it below the operating temperature, which makes me wonder how they came up with the lower bound in the first place.
