We filled our TA request out 2 weeks prior to sailing, also like you, hoping the requirement would go away. We had previously received TA within the last 2 years, therefore, did not have to resubmit the vaccination documents. We did not hear back after 10 days, so called the toll free number and they sent the TA to me while I was on the phone. Simple!
Just did the COVID test online (not required after 10/25) with OnPoint. It was also very simple. Waiting for our letter from them now. Sail on Monday!
