Does dropping below 800k baht on the retirement visa extension date violate the rules?

A user is inquiring whether their retirement visa extension is affected after their bank balance fell below the required 800,000 THB amount on August 19th, despite being granted the extension on May 19th. Community comments suggest that the balance should ideally remain above 800,000 THB for the full three months following the extension approval date, with varying interpretations of the 'three months' requirement based on different immigration offices.
