This is a slight variation on the "Alerts not working" or "Alerts stopped working" questions that pop up frequently. In my case, the alerts stopped working and I finally figured out that if I created an alert *that did not include links* they would appear on my home page and in my emails. Including fields in the message text was fine too. But if I included any links, no alerts and no emails would be generated.
Is this a bug or a "feature" or yet another arcane box that must be checked somewhere?
Note: Smartsheets is integrated into our organization and hence I log in using SSO. Not sure if that matters but it may have an impact.
