Pretty strange. I went to your link and saw the notice in red but then in the faq It says Mae Sainis open. Also date says from Sept 2022. The document I posted is not from the official Myanmar Evisa page but nevertheless it is saying fully open and it’s from Dec8. Not very clear these guys. Here’s from the evisa site faq
