So I had the same issue yesterday, we are sailing from Charleston. So I deleted the app so I can add my booster date, and it asked me did I want to recover I said yes, but had to put in all my info in again like vaccine dates(which I needed to do) answered all the question. Once I did that and went to the upload the test it gave me the clearance to upload the results. I took a picture of my test since I tested 7am yesterday had to wait for it to be verified and a few minutes later it was accepted.
