Hmmm. Looks like the Remote app needs an update, too...?

The remote app had a problem for me a couple days ago...got stuck with the "sending to car" message, so I uninstalled it from the phone, then was going to re-install to see if it fixed the problem. That time it never did turn on the fan.
Maybe I'll wait a bit before re-installing....
