What should I do if I'm still waiting for my COE approval just before my flight to Thailand?

The original poster is experiencing anxiety over not receiving their Certificate of Entry (COE) approval before their scheduled flight to Thailand, which is set for tomorrow evening. Despite having secured their flight ticket, visa, insurance, and other necessary documents, they are seeking advice from the community on what steps to take next. In the comments, various members suggest contacting the embassy via phone or email, and share personal experiences where they received their COE approval just hours before their flights. There are also discussions on whether a PCR test is required for the COE, and reminders about the need to prompt the embassy promptly given current travel restrictions and application pressures.
