Not sure what the issue is here, but I keep receiving an error with this action - I have had another user test this out on their account and it worked fine. I have notifications sent out on the basis that a value in a table has change - bother the date/time the notification button is clicked and who clicked it.
The screenshot below is saying that by me clicking the notification button to change the User email value it would become invalid? Not sure why this has become an issue now as this has been my method of sending notifications for months and another user tested it and its working fine.
The action changes the two values as such;
The email that was previously on the notification was the same email I was logged in as, so it wouldnt have changed value anyway.
