Do I need to download a full TM30 certificate for my 60-day SETV extension appointment in Thailand?

The user has booked an online appointment for a 60-day extension of their SETV and is seeking clarification on whether the TM30 document they have is sufficient for the appointment. Community comments confirm that the TM30 shown in their picture indicates it was filed properly and suggest that printing two copies will suffice for both applicants during the extension process. One user recommends canceling the online appointment in favor of going to a less crowded physical location for the application.
