Thank you for your answer. I’m clear now that I have the default message set up currently as I get whatever new annotations I add in my alerts.
It’s just that they don’t seem to be populating the variable values like I have described in my earlier comment (neither in the Alerts UI nor in the email body).
Edit: Based on @mleduc 's post/question I do understand now, that maybe, I should not expect the values to be populated in the alerts UI after all. Is that a safe assumption?
