I'm in the van at the PNR border now actually. Nothing changed just your passport and 960 baht. You will get a form about COVID symptoms together the the TM.6 form.
I tried to renew this week and get 5 years. Not possible they told me, they would only give 2 year licence based on a 30 day exemption stamp and required a visa of a year or longer to get a 5 year one.
