With much thanks to ZBob who posted below, the following excerpt is from the NY Post Article mentioned in the original post.
More than 150,000 ballots were caught in U.S. Postal Service processing facilities Wednesday and not delivered by Election Day, agency data shows, including more than 12,000 in five of the states that have yet to be called for either President Trump or Democratic challenger, Joe Biden.
Despite assurances from Postal Service leaders that agency officials were conducting daily sweeps for misplaced ballots, the mail service acknowledged in court filings that thousands of ballots had not been processed in time
In several swing states, late ballots will still be counted as long as they were postmarked by Election Day and received by Friday. They include Nevada, where 4,518 ballots arrived on Wednesday and 635 arrived Thursday, as well as North Carolina (2,958 on Wednesday and 835 on Thursday) and Pennsylvania (3,439 Wednesday and 1,459 Thursday). But states such as Arizona (864 Wednesday and 559 Thursday) and Georgia (853 Wednesday and 610 Thursday) don’t accept any ballots after Election Day.
