What does the 'under consideration' stamp mean for my COVID visa extension application in Thailand?

The user has applied for a COVID visa extension at the Ranong immigration office and received an 'under consideration' stamp, requiring them to return on April 12th. They are uncertain about the implications of this stamp and whether they need to leave the country on that date. Comments indicate that this situation is normal and that they can expect to receive the remainder of their visa period upon their return. Additionally, the user inquires about TM 30 registration status at their hotel while waiting for the extension.
