Travelling to Vietnam,

Hi guys, sorry to post in here, I've tried to research but finding conflicting info

I'm a British passport holder travelling to Vietnam on Friday for two weeks and I'm flying from BKK.

From what I've read my requirements are the following:

- rapid test

- covid Insurance

And I can get a visa exempt (for 15 days) on arrival.

Problem is I've read on other sites that they've since scrapped the rapid test and that a BNO (British national overseas) cannot apply for a visa exempt on arrival?

If anyone that's done this recently or is just better informed than me can clarify this for me id greatly appreciate
