I emailed the hotel to check, and ask for official confirmation, this was their reply, which I will use in evidence if needed.
On day 5, according to the new rules, you must be examined. But it's an ATK test, which you have to do yourself. and self-report results through the application "MorChana". This rule is effective immediately. and has retrospective effect on people who book through Thailandpass Test and Go system who have received QR code previously. (All details Please read carefully interpret and understand the link I sent earlier).
I understand your point and agree with you. But it would be great to get that refund.
I'm happy to take another ATK on day 7 or 10 and self report, as it will support my case if needed.
I've just read the other confirmation of this day 5 change for arrivals in the liminal dates.
