Onstar remote start on app does not work. when I download the app get an error code of 705_1(unexpected server response. Please try again. If this issue persists, please contact support for assistance.) Then when I try to use the remote start get error of 220_99 (Remote Start count not be completed. Attempt Remote Start from the Key FOB or drive the vehicles before trying again) Usually it will work maybe on the second try but it takes awhile for the error occurs so sometimes I'm at my car before I can try it again. I've uninstalled/reinstall the app. Used the FOB to start and drove vehicle. Called Onstar and no fix. Dealer indicates it's a known issue but no eta on fix
