Actually....

The problem didn't slow down counting, it slowed down voting, causing large lines. Those large lines were well reported on election night.

I followed them with a chuckle on election night. If you try Googling them now, you'll find very little and a flood of algorithmic comment-slide, pushing articles reporting concern over the separate issue of delayed counting, which is a confusing misdirection if you were searching in interest of the voting delay issue.

The problems were with the voting tabulators, where you stick your ballot in at the polling place. The timestamps were printed too lightly and when people stuck their just filled out ballot into the tabulator, it was rejected. They'd try different tabulators that were a little more sensitive, causing a bottle-neck of assuming some tabulators were bad, until they determined the problem, and re-configured the printers to be darker.

It caused people voting to have to wait and created large lines in some places, such as Anthem, where voters were reported waiting for hours.

Maricopa County was possibly hardest hit, with many locations. Yet, with the prevalence of early, mail in, and other less verifiable voting methods, the in person voting issues didn't affect a larger percentage of voters, reportedly about 17K ballots in were affected in the larger county. One could reasonably speculate that it did disproportionately affect traditionally conservative voters, due to the some of the counties' leanings and the distrust in non-in-person voting.

"Maricopa County has identified the solution for the tabulation issues at about 60 Vote Centers. County technicians have changed the printer settings, which seems to have resolved this issue. It appears some of the printers were not producing dark enough timing marks on the ballots. This solution has worked at 17 locations, and technicians deployed throughout the county are working to resolve this issue at the remaining locations," https://t.co/Og7bXf0CsV

It is reported that they eventually fixed 55 of the 60 locations....in that county.

..but it is true that the meme is low effort drivel, like Trump concern trolling memes people would worship on Twitter.
