Can I apply for a COVID extension at Chaeng Wattana after canceling my Non-ED visa?

The user is seeking clarification on the process of canceling their Non-ED visa and applying for a COVID extension. They want to know if they can complete both processes at Chaeng Wattana or if they need to go to Muang Thong Thani for the COVID extension after cancellation. A comment confirms that they can cancel their Non-ED visa and immediately apply for the COVID extension at the same counter in Chaeng Wattana.
