It’s not clear that it was EVER effective in any decision-making. In the early days, there were so many false-positives (WA State) that I pretty much know nobody who cared. And so many false negatives that you had to test ANYWAY if you had any symptoms or any personally-known exposure.
The problem is the app gives NO indication of duration or intensity of exposure, nor of the timing of the person you’re exposed to.
Almost pure theater—caring about the appearance of safety, not actual safety. Good Riddance.
