Yup, I missed the arrival testing requirement when I went in August. To be fair, at no time was this ever communicated to me. Turns out it was on the Quarantine Exemption certificate that I got in my email... in Korean, which I don't read/write/speak. Since my visit was so short (about 50 hours), no one ever caught it (including me) until after I left.
When I went back with my spouse earlier this month, we had our arrival test scheduled at the airport. Very easy.
In fact, I only caught the arrival testing requirement the second time because my spouse's Quarantine Exemption certificate was in English and he asked me about it!
