I have a 1 year AO visa multiple entry and I reported the 90 days online. All worked well. I left Thailand mid April via Suvarnabhumi Airport. Before I went through Immigration I asked an officer if I needed a re-entry stamp or document but he lead me to the Thai immigration row. I got the usual stamp showing that I've exited Thailand. I would think that there's no further 90-day reporting required since I'm back home in Europe but last week I've received an email where they reminded me to report the 90 days. How is that possible when I have left the country? What should I do?

Also it's a bit unclear what to do on the website as there's no mention of notifying them that I'm abroad. And what's the usual thing to do when I stayed in Thailand? Should I then click on 'New Application TM47' each time I have to report?

Thx
