Setup Home Screen message appears after unlocking the app

I've had the same issue for several months. Even though my 1Password iPhone app — including the Home screen — is correctly set up, and usually displays my Home screen correctly, it often displays "Set up your Home screen" instead of the Home screen. Sometimes the "Set up your Home screen" message only displays for a second or two, before my correctly set up Home screen spontaneously appears. Other times, the "Set up your Home screen" message remains, and I have to click around to other screens first, before the correct Home screen is displayed.
This behavior persists through iOS software updates, restarts, etc.
A family member also has the same issue with their iPhone 1Password app.
