I was excited to see the Share for Review feature roll-out in the newest June 2020 update. However, I have already experienced issues.
1. It only exported one page in my document.
2. I 'invited' members, but when they got the link, it prompted them to enter a password (that I never set and don't want to set).

I work with a lot of non-technical savvy folks who just need the ability to see my work and comment without the need to log in or create an Adobe ID. Forcing them to do this will alienate users (our clients) and will in return ask us to go back to sending emails.
