Saving Nitro to Google Drive

[Mary Chatham]

Good day. I need assistance with Nitro Pro 12 Pro and saving to Google Drive.  My new employer uses Google Drive for her storage and file management.  When I open a pdf document with Nitro and try to save it to Google Drive, I get a pop-up that says to sign in to Nitro Productivity Suite.  I have no idea what that is, and I've been using Nitro since 2010.  When I put my email in that box to sign in, it tells me to check my phone.  It sends a message to my phone asking if I am trying to sign in by another computer. When I click yes, the computer screen asks me what number is on my phone, but it doesn't send any number. It just sends the question about whether I'm trying to sign on with another computer.  Can you please tell me how to save Nitro pdf docs to Google Drive?  Thank you.
