DaVinci reverted back to 19 from 20?

I upgraded to DaVinci Resolve 20. I have full version. Started playing with some new features last week. Now when I open the program it's version 19 again. I've searched my computer and can't find 20. I'm so confused. Please help.

What happens if you de-install Resolve 19 (using the "Uninstall Resolve" app), then re-install Resolve 20?

If you're on a Mac it's possible you have both the Mac App Store version (v19) and the one downloaded directly from Blackmagic (v20 beta). If so, you'll have two DaVinci Resolve apps with icons that look exactly the same.

I don't see an "Uninstall Resolve" app. Is there another way I can uninstall it that will work? I'm not even finding 20 on my machine anymore. Maybe I should try to reinstall it again? I'm worried about ending up with multiple copies of everything just making it more confusing.

I am not on a Mac.
