Wyse Beta freezing on intro page (cyan blue/green) screen

Wyze beta app is freezing on all my (7) Android devices except the one with Oreo on it. Some are Lollipop and Marshmallow and I have no Nougat device. I have the latest 2.3.12 update. Anyone experience this?

Update: Uninstall and reinstalling restarted the app again but I’m curious to know what happened in the first place.
