Mine has just come through too - a shade under 48 hours. Pretty impressive, although, given my first flight is at 07:30 tomorrow, I would have been having kittens by now if I hadn't already got a COE.

Someone on one of the other threads noted that some people got their Thai Pass approved in a matter of minutes and speculated some kind of AI may be employed. I wonder if they're just letting a percentage of applications go through without any checking, on the possible grounds that one would have to be pretty stupid to turn up with a Thai Pass, but then be unable to show supporting documents if requested to do so.
