I figured out what to do. I removed the Roku app, then reinstalled in. This required me to login again. The app required me to enter a 4 letter activation code at the watch.redeemtv.com website, which I accessed via my phone. But before it would let me enter the code, Redeem sent me an email to confirm my email address. Once that was confirmed, I could enter the 4 letter code. It took the Roku app some 10 seconds or so to acknowledge that. Inside the Roku app I then went to Library, Within that, beneath My List, was a new category called Purchases. The Additional Donor Content (all of it!) was now there and I can watch it on our TV. These steps should be provided to donors in an email, I think.
