You may get a call to organise a house inspection/visit neighbours to check. They may do it by line or WhatsApp. Go back on 16th May and get the rest of the year extension.
“should be easy” will go down in history. Absolutely nothing wrong in trying. How far that will go will be subjective. So far this month 5 people have managed to do so in Phuket. I guess way more have just bounced out and got another 180 days.
The first report after entering Thailand needs to be done in person. Subsequent reports can be done online. But for the DTV that generally means most if not all will need to be done in person as you have to leave by the 180 days (unless trying to get the golden extension ticket )
