Exactly. The "expert" responses here don't make sense. They keep saying "you can't upload a pdf", rather than stating "that feature is not working at this time". Either they don't know that during the process we are being given the option to upload a pdf through the website, making them pretty terrible "experts" or they are pretty terrible at communicating what they are trying to say.
I had this same issue last year, so when the same issue occurred this year, googling the issue led me to this thread. I am experiencing the exact same issue that you documented in your screenshots. I am given the option to upload a pdf but it gets stuck on the "scanning for viruses" part and I had to go back and enter my information manually. Not the worst thing in the world, but if the feature isn't working then it should be removed.
