Just want to share my experience
I'm back to thailand after i stayed out of the country for almost 7 months. I have applied for a SETV in my country which it has been approved in less than 24 hours. When I went trought the passport control at the immigration at bangkok airport, I gave my passport and my printed TDAC to the officer. He looked at my passport pages and he asked me a few questions, what are you doing here and for how long are you going to stay here. After I answered right he stamped me in. Everything easy, no issues. This is my 6th tourist visa by the way 😉. I come to thailand since 2017 and i have had different types of visas during these years
As i am still far away to reach 50 years old i am considering to apply for 5 years DTV next time, as i already have the necessary funds requirement
