Azure DevOps (formerly VSTS) in general moves really quickly, relative to everyone else. At least it feels that way... the multiple names to search for (vsts, tfs, "azure devops") also makes it hard to find stuff in general searches. Often the results are prior versions, and it's still hard to figure out.

I dread when I have to tweak things. I do appreciate the service(s) a lot though. Pipelines is one of the better CI/CD platforms I've ever used anywhere. It's just, like you said, sometimes hard wrt documentation.
