I have some Cards and Controls that are not loading. I need to figure out why they won't load and also set some type of alert/notification when they don't so I can fix them (hopefully before a user accesses them).
I don't think there is a way to be notified that a card doesn't load. To fix the issue, edit the card and the issue should be highlighted when you are in Analyzer. I have also seen this happen when the dataset has not been accessed in a long time. To fix this, you need to go to the dataset and click "start" (I believe) to have Domo make it accessible again.
