Didn't realize QR reader didn't work on PE as I usually use my phone for QR.
I did find actually a different fantasy sports apk that apparently can control yahoo and espn. I had to double check it after I realized it wasn't from yahoo lol. Hope if runs on the PE for you.

(Look for the download link near bottom of paragraph. Not the green advertisement Download button on right.)
Another yahoo possible one. PE untested.
Fantasy Guru apk
Finally found a non QR download for yahoo 11. Its runs on PE so far, but its one update behind current. This is 1.5, current is 2.0.1. Can't find 2.0.1 download, main difference is the new version allows for Google and FB signin, 1.5 only uses yahoo sign in.
Yahoo FFB 11
Good luck, it was rough finding just those lol
