Yeah, that is a totally reasonably explanation. And I understand that they are still figuring out the best way to proceed. I just wanted to share my frustrations and experience with this because the original post made it sound like none of us were on unity 2021 yet, nor should have been. Maybe that is the intended path for working with the entities package, but my experience with other preview packages led me to believe otherwise. I understand there is a preview label on the entities packages and things like this happen. I look forward to hearing more about their plans for future versions. I decided to downgrade now because I thought that an issue I was experiencing was possibly one of the incompatibilities with 0.17 and unity 2021. Turns out it wasn't, but now I'm hopefully in a better place to upgrade to future versions of the entities package which I have been looking forward to.
