I did exactly like you. I'm Indonesian, came to Thailand on December 2021 with TR60+30 days ext+ 1 time Covid extension then left before my visa expired. 2 weeks after that I came back here using my free 30 days exemption, and at DMK airport the immigration officer (3 of them) came to me when I was in the immigration counter and asked questions regarding my previous 4 months time here. What did I do and if I'm a tourist, why did I need 4 months to be inside the country. I explained everything, showing my return ticket, bank statements, and insurance, and they finally stamped my passport and let me in. I think that's mostly because those 4 months was considered as still in the COVID rampant era and it's unsafe to travel around or outside. So I'm not sure how the immigration will be with the situation is better for travelling now.
