Rapid antigen tests have high rates of false negative results. Repeat testing is needed to confirm.

While true, they’re quite effective for point in time “am I contagious at this second”

If you’ve got antigens in your nose, you are shedding.

Rapid antigen tests commonly give false negatives. They are better thought of as tests to prove you have COVID, not tests to prove you don't. You need multiple tests if you're sick and want to be sure it's not COVID. Time is only part of it.

Actually, your experience is spot on. It's recommended to wait 5 days to test if not symptomatic sooner. Earlier tests are not expected to accurately detect the virus.
