Thanks again for helping me figure out how to send a notification email from Power Apps when a new request is submitted. I now have a need to send a notification email to the requestor and Mechanical Engineer assigned to the project when a new comment is added to the project in Power Apps. I tried leveraging the block of HTML email and OnSuccess formula you helped me with before, but since I am now dealing with a parent/child list relationship, it is a little different.
I've attached a doc that hopefully provides all the information you would need to assist me. Let me know if there are any other details you need. Thanks in advance for your kind assistance. No huge rush on this if you are swamped with regular work.
