In 2023 I went to a Thai embassy in the country where I was residing to get non OA. I went 13 times (luckily I had a very tolerant employer who let me shift my work so I could make my visits) since the same person there kept giving me more and more steps to follow. I had a 1 year rental agreement and the approved nonOA insurance purchased and proof of funds etc. I even had my flight booked and nothing I did could get me the nonOA or nonO before my move to Thailand.
I suspect that I might have been the first person at that embassy seeking a nonO and they did not want to submit my paperwork with any errors and lose face. She finally begged me to just take a multiple entry tourist visa for six months and begged me to just deal with nonO when I reached Thailand. My Thai friends were appalled that there was no way to sort this before my flight but I had given up and just accepted the METV. Luckily, at that time, I was able to find a bank branch (after many bank visits), that would let me open the account and then start the NonO application.
