Bought the drone core on ebay in working condition , flew it about 10-15 times . i connected the controller to my wifi and noticed a new update on all 4 products the stabilizer , drone ,camera and controller . On the following day i connected everything like normal and noticed the drone wont connect to the stabilizer , it just flashes a red power button . I've tried everything , even with gopro support team . Gopro has one of the worst customer services ive ever had to deal with. I asked for a little help on a new core to see if this will solve the issue and nothing manager said it has to be a defected harness, after explaining i returned my Karma Grip to make sure. Has anyone on here had this issue ?
