Using IOS version of APP - last night I kept getting "exceeded max distance" message. Flying in beginner mode and I was either standing next to aircraft or it was much closer than 90 M - once this message displayed I was unable to fly forward until I landed and restarted aircraft. Kept getting message to 'recalibrate MC setting". I have no idea where MC setting are in APP (never found MC settings) any help out there I am on current Phantom software and new APP (prior to new app all went well)
