Verifyle is a bit clunky like that, too. One has to list each person as an account and it has to be (I found out later) the name as on the return. William, not Bill, for example. There is an editing tool whereby a couple can e-sign the second name but only 2 couples could figure it out. I could not but forwarded the instructions, such as they were, received from Verifyle. Some, actually many, folks are so much more technologically astute than I am! At least one couple printed out the 8879, signed, scanned, then uploaded to the portal but not everyone has a printer and/or scanner.
It's always something!
