Linda, I did, but still had to complete the paper form at the airport. I showed them the Verifly app, which showed that I was ready to fly, but they still required me to fill out the paper form, and to check in at the counter, even though I had a boarding pass on my phone and no bags to check. Although now that I think about it, that form may have been a contact form, not the attestation. I also filled out the contact form online though....Seems there's a lot of duplication of effort.
