When I spoke to them. They told me to reinstall the app. Bingo! The link was there waiting for my ATK result. The hotel concerned was the Jasmine Hotel. Phra Khanong. Fantastic service and help.
I contacted my hotel on the 5th day. They told me to reinstall the app. Which I did, and on the notifications there was a link. Where it asks for number put ATK. Then send. My status went to green again.. The hotels don't really want to deal with it. The app us simple enough.
I have just had my fit to fly PCR results. I was not going to take any chances. Thai Airlines are still saying they are required. I feel a lot better knowing I am starting my journey clear.
