The reminders aren't a problem for Chaengwattana. I received mine a week ago and registered the TM 47 online the same day. Still, I wait. The wait wouldn't be a problem, except that I don't want to go past the date due and then make a 46km trip to Chaengwattana. Mail, which I used for most of Covid, was never a problem. They always managed to do that timely enough. Mail, of course, is more of a problem for them, which leads to the question of what don't they get off the rocker and process the existing 90 days waiting for approval.
