Is there any where to see when my account version was upgraded to 2020.2?

when as in what date exactly? or are you wanting to know if it has updated yet?

I am in my account, and I was wondering if it was listed anywhere within the account the date the version was upgraded to 2020.2

On your Home Dashboard, scroll down to the bottom, you should see a footer showing the current version of your NS account.

Yeah i know the current version...
