When is my next 90-day report due after a one-year extension of stay in Thailand?

The user is inquiring about the due date for their next 90-day reporting after applying for a one-year extension of stay in Thailand. They received an extension granted on August 28, but are unsure if the 90-day report is due 90 days from the application date (July 29) or from the date the extension was granted (August 28). A community member responds that if this was the user's first yearly extension, then the 90-day reporting is due 89 days from the application date. Conversely, if this is a subsequent extension, then the reporting should follow the previous reporting schedule.
