Yep... it depends (a bit) on the Embassy where you apply... some take it, some don't. Same with medical appointments and/or cooking class. Some are okay with 14 days, others want to see at least 3 month. And so on...
P.S.: Maybe you could ask the Immigration if it's legal to work "remotely" from Thailand without a DTV (or a Work permit)... you might be surprised about the answer... 😏🙃
It's still wrong what you say... the DTV is for people who want to work here... but... not in a Thai company or with Thai customers. Remote work for a foreign company is legal now with this visa, that's the big difference to before.
