We’re working to fix this bug, which can occur with Apple users (iOS 14.2.1 and later). Simply reopen the app. Note that this issue only occurs if the app is already open in the background.
Why do I have to reauthenticate when I leave the Hilo app open in the background during a challenge?
Sometimes, when I open my app, the tiles don’t show the actual status of my devices, and some of control buttons are no longer visible.
