Event Registration Emails not sending

[[email protected]]

This client has currently has several events active right now. Originally registration emails were sending out fine. At some point they appeared to have stopped.

The event I was testing was "2021 - Donor Trip - Labyrinth Canyon"

• I signed up for the waitlist registration level (my name is Chad Harris)
• I was successfully added to the list of registrants
• Email Log does not show an email sent to me

I recently requested the upgrade assistance in case something about the package is at play. I am also curious if something about Salesforce Guest User Permissions or Permission Sets are at play? I've added all necessary users to several permission sets but not sure how to check guest user permissions.
