Request Participant / Approver not getting notifications

[Adam Hardester]

Hello,

I created a new service project and created a workflow that requires an approver to approve. I am able to test successfully approving the status myself along anyone who has a Service Desk Team account. I then spun up a new Gmail account to use a test customer account. I do have the helpdesk locked down so only customers I invite can access things. I made sure to add the test customer account to the project. 

I tried adding the customer as an approver and no email is sent to them. I also tested by adding that customer account as a Request Participant and the email just never comes to the account. 

Everything I'm reading online is telling me I should be able to have a customer approve a ticket. 

Everything appears to be configured right on the customer notifications screen.

I'm wondering if the two missed email notifications are related. It seems like I should have gotten two emails, one for request participant added, the other for approval required.
