Confusion over Upgrade Protection

I apparently purchased the Upgrade Windows Protection when I upgraded to Draw2019 at the end of last year. And only now remember it because I just got charged for it again. I was about to cancel it, but wanted to be sure the program would still work. I can't remember jack about it. Searching around, my general understanding is that if I were to cancel it, the Draw version I have would just stay the version it is. The thing is, it's already the version it has been all year. Was I entitled to it being upgraded to 2020 before now? And if I don't cancel, will I be entitled to Draw2021 whenever that is available? And how am I made aware of this? Telling draw to search for updates gets nothing, I have no emails? I'm really confused on what Upgrade Protection is or is not doing? Or what I'm supposed to do with it.

I apologize if this is somehow staring me in the face, but I can't seem to find the answer. Any help is appreciated.
