I posted rules regarding need for TM30.
That was reply to another poster.
Along with clarification for others.
You stated ...
"IO did not to process my visa extension without an update to the "Notification of address" in my passport."
I cannot help you with your immigration office.
TM30 should not be required for extensions.
The fact that Korat is rogue office is your issue.
Why complain about my posts as couple of others have.
Your immigration office sets your hurdles.
I'm outlining correct rules re TM30.
Your post also included this...
The answer was very clear:
"Just start to count for 90 days at the date you enter the country and report then for 90 days stay".
That refers to tm47 and was not my post.
