Have Avast M Security for 4 years can't add replacement phone

[REDACTED]

We've had Avast Mobile Security since 2013.  Recently we replace a broken phone.  The broken.  I sent myself a download link from the my.avast.com portal to add a new device and installed the application.  I can't figure out how to tie the new phone to the existing my.avast.com account so I can manage it like I do the other 3 phones.  This happens when I try to install the Anti-theft feature.  I've already enrolled my email address in the app on the new phone and it recognizes it until I try to install Anti-theft; it seems to want to use a google account for the pin (but I have a pin enrolled to a non-google account.
