@Elie ********
it’ s the case like that for approximately everyone and here in Chiangmai until the beginning. Pay the amount of 1900 bahts receive 15 days and a stamp under consideration, you come back and you receive 45 days more ( usual procedure) or if it is refused (rarely) a stamp for 7 days to leave the country. Be happy because here without a letter of your Embassy you have very few chances to receive a Covid extension again and that stays under the appreciation of the officier of immigration . It’s a privileged that Thailand give, not a right. So be happy to receive it
