UPDATE: Received my approval in 60 seconds once I uploaded my QR code for vaccination (thanks to Stuart Cummings clueing me into the glitch - solved it by leaving a border around the QR code)
I applied for Thailand Pass on Nov. 25th and am flying on Dec. 3rd. Still don't have approval but was able to get a QR code for proof of vaccination which I didn't have before. When I asked about adding that to the application I was told I could not. So question is - wait and be patient OR should I submit another application with the vaccination card AND QR code (I'm not sure if this is what's holding it up or just it takes the full 7 days).

Community members advised resubmitting the application with the QR code, sharing personal success stories of receiving timely approvals after doing so. Ultimately, the user successfully received their approval swiftly after uploading the QR code.
