Others have had this problem, but I've tried all the "fixes", none of which work (re-boot, re-install the app, turn off VPN, ensure that the latest iOS version is installed, etc.).
I had the problem once before. The app failed to load for almost a month and then, all of a sudden, it started working again. Although the key card works, the app is much more convenient and provides access to features remotely.
