you write a letter from yourself as the business owner to yourself as the visa applicant. May seem strange I know but that letter is a fairly basic requirement. It should give you explicit permission to work remotely from Thailand.
It sounds like you gave way to much information on the tourism aspect and not enough on the work aspect. And best to ignore ChatGPT. For workation you need to emphasise how you can manage the resort remotely, you also need a letter stating you have permission to work remotely from Thailand and of course show financials. So invoices/receipts matched up with bank statements would help, but also that it pays you a regular income which you can show. Also helps if you show you are registered to pay tax and supply tax returns
Was it rejected or cancelled? If it was cancelled it implies an error with your bio data. If it was rejected how long was the course for? Did they ask how you will support yourself and if so how did you answer?
Anonymous participant hardly the purpose of the DTV. You don't qualify for the workation option. I guess you could apply under soft power but they might not give it to you looking at your work schedule
Why on earth did you apply under soft power then go on to tell them you work remotely. No wonder it got denied. If you work remotely then you must apply under the workation option, no other choice. The visa is issued for a purpose and you didn't meet the purpose. You can't apply for soft power then legally work remotely from Thailand
More and more consulates are asking for this due to so many people trying to ignore the rules. Stay in the area served by the consulate you applied at until the process completes
