This issue is reproducible by simply opening the app on one network (like your mobile data) and then move to a new network (like your home network). The app will fail to get or change statuses and the section that shows Nearby Incidents and Event History will fail to load.
To fix, you close the app and re-open it.
Really inconvenient when getting home and the app is fouled up.
FYI - I’m on ATT with a G S9+
