Just to say that the 90 day on line reporting is a bit erratic. After 6 successful reports, living in the same house and not having left Thailand, the latest one was 'not approved'. Off to Promenanda in Chiang Mai where the Immigration officials just smiled and said,' it sometimes just doesn't work'. nothing that I had done, I filled in a paper report there and was out in 5 minutes.
TLDR : Answer Summary
