Do I need a new soft-power activity for each return visit on a DTV Visa in Thailand?

The conversation revolves around the DTV Visa in Thailand, specifically regarding entry and re-entry based on a Muay Thai invitation letter. Participants indicate that there is currently no requirement for having an ongoing soft power activity when entering Thailand. Immigration reportedly does not check the status of the previous invitation on re-entry, although it’s acknowledged that they can technically check anything they want. Extensions within the country do require confirmation of an ongoing activity.
