Accuracy? – MI COVID Alert Review

Not sure how accurate the app is. I live in a CCRC with a nursing home and independent living. I was in the main building last Friday getting my first COVID-19 vaccination within spitting distance from the part of the facility where we have had multiple positive tests and several fatalities and I never got any sort of alert from the app. Perhaps I’m expecting too much.
