Hi!
Earlier this month I put up a blog post detailing the several requirements for triggering Workflows. It’s just a more detailed explanation of what it in the Docs, since I find that sometimes users get confused when they are still not very familiar with the concepts.
Since my blog had been essentially stalled for a few years, I guess coming here and warning people about it might be helpful.
Thanks for this initiative of the new Show and Tell Category
