So, I entered last night via Suvarnabhumi.
I was required to download the AOT app to my phone and to submit the health questionnaire.
No Dr. Certificate or Proof of Insurance. Since the Dr certificate required the formal test ( which is almost impossible for healthy people to obtain in America ) this probably means the travel from the US is now impossible. I have been unsuccessful in getting my insurer, Cigna International, to issue the required certificate anyway.
Temp scan was the only other measure.
What becomes of those of us here on short term Visas remains to be seen for now.
TLDR : Answer Summary
The post shares a personal experience regarding entry into Thailand via Suvarnabhumi airport, highlighting the requirement of the AOT app and a health questionnaire. No doctor’s certificate or proof of insurance was requested, making it appear that travel from the US may be challenging due to the difficulty in obtaining a required doctor's certificate.
