What are the new mpox reporting requirements for travelers from Africa/South America arriving in Thailand?

Does anyone have experience with the new mpox reporting requirement when arriving from Africa/South America? From what I understand the yellow fever, T8, online registration is to be used. From my experience registration is straightforward and you will receive QR code approval by e-mail. When inquiring Ethiopian Arlines, they inform the T8 registration will be verified to allow check-in. Again from experience with the yellow fever registration but before talk of Mpox, when arriving at Bangkok, the health department would scan the QR code and issue a slip to be presented at immigration, for me it went pretty smoothly every time. Any new experiences?
