Came home from a trip to Vegas yesterday and put the car in the garage with the summon feature using the key fob. Worked fine. Two hours later, I went for a short trip, returned home and found the feature no longer worked using the key fob. The IOS app on my iPhone still works fine. Tried using my wife's fob and it was also unresponsive. Looked at the settings this morning and noticed the 'Customize' option, when pressed brings up the 'Continuous Press Required' tab, but it's now grayed out with a note saying 'Continuous Press required in this region'. That's fine, except it's not working at all. Has there been a sudden upgrade which is preventing the fob from activating the feature?
