For me, all of the current status information and most of the functions on the Connected Drive app work EXCEPT for remotely setting a departure time, activating a charging schedule and the Climatize Now function. For those functions/commands, I get a timeout error message after a couple of minutes stating that the command could not be executed. Clearly, my vehicle is communicating with the BMW servers, but it is puzzling why some features are working but others do not. I am considering pulling the fuse and resetting the cellular modem, but I am concerned that it might make the situation worse.
