I just got my Thailand Pass QR code approval for the Test & Go.
I'm from the UK so have a NHS vaccine certificate. Flight is on 11 Nov.
1st Application (Nov 1) - Used an Outlook email and heard nothing back.
2nd Application (Nov 3) - Used Gmail and received a confirmation but nothing else.
3rd Application (Nov 3) - Used another Gmail but cropped the QR codes, confirmation but nothing else.
4th Application (Nov 4) - Used Gmail and cropped QR codes again, make them clearer. Didn't use the AQ method like some here, was going to wait a bit longer before doing that. Confirmation but nothing else.
Nov 5 - Called Thai consular service and spoke to the staff, gave my application details. Heard nothing else.
5th Application (Nov 6) - Used a totally different email, cropped QR codes again making sure there was enough white space around them. Received confirmation.
Emailed Thai consular email with all my information. Heard nothing.
10 minutes after emailing them, received my QR code for Thailand Pass, to the email used only in my latest 5th application. Nothing heard from the other applications. Hope this helps anyone.
Not sure what did it in the end but quite likely the email to Thai consular support got my application looked at immediately. That or leaving some white space around the QR codes. Good luck to all.
