Do Thai embassies wait until close to the flight date to issue DTV visas?

Hi , I applied for a DTV visa through the London Embassy last week via the soft power route. The next day the embassy responded asking for my booked flight confirmation. I booked a flight dated the 31/10/25 and uploaded the confirmation to the e visa site. The next day the status of my application changed to processing pending approval. It has now been a week since the last update and the status of my application has remained the same. Do the embassy wait until it's close to your flight date before issuing the visa?
