We have had 2 different instances this week where users have been blocked because they do not have the Vicarious Emails permission. This hasn't been a block for us before, and I was unaware of this permission. After researching a bit, it looks like this permission was released in the 2021.1 release to allow for scripts to send emails on behalf of someone other than the user in question. Has anyone else run into issues with this permission blocking their work?

I first became aware of it today, after we had a production problem caused by [lack of] it

We've encountered this recently as well and have found the following doc online stating that as of August 2021, "these exceptions will no longer simply log the warning, but will throw an error"
