Just a quick FYI as I know people are asking about this on this group:
I've asked a contact of mine at Bangkok Chaengwattana about whether the 90 online reporting system is down or somethings wrong since I submitted my online report Tuesday evening (15th Dec) and still had no approval (Friday 18th).
Msg back was: They're backlogged after the long weekend and currently clearing submissions up to the 14th Dec, as of today.
Hope this helps (I don't know more than that)
Cheers
TLDR : Answer Summary
The 90-day online reporting system in Thailand is experiencing delays due to a backlog after the long weekend. Reports submitted on or before December 14th are currently being processed, which may explain the lack of approval for submissions made after that date.
