This morning, I'm watching Good Morning America, and there it is on the news crawl across the screen: Many people can't order the free government tests from the site due to an address snag for people living in APARTMENTS at the same address.
Sure enough, I test the site and ONE lucky (first) person used our address already and the REST of the hundred or so of us can't get the test kit as “At-home COVID-19 tests have already been ordered for this address. We are unable to process duplicate orders for the
same address."

It doesn't matter how or where I input the apartment number. (There IS a separate box to list it.) I'm using the way the USPS wants us to list our address and it doesn't work.
