Yup. Machines in heavily red area in east valley are having extreme difficulty reading ballots (ex. "ink not dark enough" on the printed ballot[?] despite having been adjusted for the issue).

Mine went through the 2nd machine on the 2nd try (after 4 tries on the 1st machine). Companion had to spoil and redo, but that one went through with no problem.

So, keep trying - better than giving up and/or going with some other, more manual option.
