To be honest, I wonder whether "ASEAN NOW" can't use its good relations with the immigration authorities to point out the "90 Days Online" problem or. the dubious, unfounded rejections of applications after correct reporting ("Your application for "STAYING LONGER THAN 90 DAYS" has been rejected. Incorrect entry date upon entry into the kingdom/Incorrect visa expiration date.").
After all, it is now being discussed in three topics and there seem to be dozens of forum users who are affected. I only ask because it is next to impossible for individual applicants to find a solution to the problem. For example, I tried to explain the problem to immigration and was immediately turned away on the grounds that they couldn't help me and that I should report from now on by visiting instead of online.
