Has anyone with a valid DTV needed to show proof of funds recently?

Recent discussions reveal that individuals extending their DTV in Thailand are indeed required to show proof of funds. Multiple commenters confirm needing to demonstrate that they have maintained a certain amount in their bank accounts, with varying amounts suggested, but one confirmed requirement is holding at least 500,000 Thai Baht or its equivalent in another currency for a minimum of 30 days prior to the extension application. Additionally, showing bank statements and possibly an online banking app may be necessary during the application process.
