Yes. Absolutely report it. I had a very similar situation happen to me and I wasn't sure if I should report it. I decided against it and regret not reporting every day. That's unacceptable. We spend months and countless hours of our lives preparing for this test and pay an egregious amount to LSAC. They should have their stuff together. This is your future we're talking about.

I'm also applying this cycle. I've decided no matter what my score is I'm submitting and going. I took a gap year for work with the intention of studying but ended up working wayyy more and studying was less than I wanted to. So I'm taking my score to whatever school will take me. They say it's not where you go but what with you do with it.
