Apple have made a change to the way Wi-Fi Accessories are setup in the 14.2 release of iOS. Because of this the way Yale Wi-Fi Bridges are setup on iOS has also changes.
iOS has functiontionality that allows Wi-Fi devices to easily be connected to your Wi-Fi network without having to re-enter the password for it. This functionality is called WAC (Wireless Accessory Configuration). Within iOS 14.2 this functionality is not functioning correctly, we expect it to be updated in future versions. Until then we have changed the app to allow Connect units to be setup.
Before setup, please make sure that you have a 2.4GHz Wi-Fi network running in your house, which your iPhone is connected to.
