Where have there been technical issues so far during US midterm elections?

US midterm elections: Voting machines malfunction in New York’s Westchester County A handful of polling locations across the United States have reported some technical issues with how ballots are cast during the midterm elections , causing officials to delay the closing time for polls so votes can be cast. In Westchester County, New York, north of New York City, officials said the machines meant to automatically read physical ballots were having trouble because the paper the ballots were printed on was too thick. Al Jazeera’s Kristen Saloomey, reporting from Tarrytown, New York, said election officials were collecting ballots to be counted later manually.
