When I approve an encounter there are supposed to be emails sent to the person who uploaded and the photographer. No emails are being sent.
What did you expect to happen? - Email notifications are meant to be shared Submitters & Photographers once the encounter has been approved.
What are some steps we could take to reproduce the issue? You could try going into an approved shark (such as R1066), change status to unapproved, edit the contact information and add your test email, then hit save, close editing, and change the status back to approved, and see if the email notification is sent.
