US 2020 Election: 'Technical flaws' prevent ads from running on Facebook

Less than a week before the election, the Democratic Party reported that Facebook's social media advertising systems had prevented the campaign from running some ads, allegedly resulting in the loss of more than $500,000 in potential campaign donations.  

According to Facebook, the flaws resulted from a change in its political ads policy for the final week of the campaign. The policy change was intended to prevent political advertisers from uploading new ads in the week before Election Day, but it inadvertently prevented pre-approved ads from running.
