Has anyone else had problems with their fingerprints not being authorised/recognised? Yesterday at Seatac for the 4th time out of 6 entries I had to get a CBP agent to authorise my entry. He was very helpful and showed me what he said was the best way to get fingerprint recognition but it still didn't work. It is quite irritating. At least I wasn't shunted into an immigration room as happened to me in Miami. Wondering if I should go and get re-fingerprinted.
