I have a Non O Multiple Entry. I entered Thailand on 5 May. My 90 day report was due 2 August. I did the online report on 27 July (7 days early). Today I received this email advising me that my report has been rejected as submitted "more than 10-15 days in advance" I understood you can submit up to 15 days early. I'm also confused by the resubmission date they advise 07/09/2023. Just did the report in person at Chamchuri Square. Officer said an immigration officer had put my entry date as 10 June. That's why the rejection advised me to resubmit on 7 September.
