Some information if you are trying to do 90 Days report on line for Bangkok.
I always use online with no problems until now. Could not complete report and tried for 3 days on website and the App.
Had to go to MTT today. My 12 month extension for Non Imm O retirement was done 1 Oct to Nov 2021. Seems they are having trouble updating info at the moment. So I was showing as overstay. Also told the App is not working.
Pre booked appointment so in and out quickly but poorer by 600 baht in taxi fares. LOL.
