What are the requirements and tips for applying for a remote work DTV visa in Thailand while in Vietnam?

Anybody recently applied and got approved for DTV while in Vietnam, through the e-visa portal? Particularly for a remote work visa.

Have some questions as i am thinking about applying myself. I've tried googling the answers but couldn't find anything concrete. Could use some help before i pay the non-refundable fee and then get rejected.

1. How old was the bank statement that you used for the showing of the equivelant of 500.000 baht? I have one from August where it shows 15.000 euros, if I print one out now, i would be a bit short (12.700 euros currently in my account).

2. I have my employment contract, however, it doesn't specifically state that i can work remotely. That is an agreement between my employer and myself. Would i need an additional letter stating the approval to work remotely?

3. I wanted to include my payslips when uploading for the financial requirements, but it seems that you can only upload 1 document, is there a way around that, or do you get the option to upload additional supporting documents later in the workflow? (I haven't gone passed the uploading files screen).

Any information would be much appreciated. I am currently in Vung Tau, else i would go to the consulate general in Ho Chi Minh City myself.

Thanks for taking your time in reading this.
