Jeff Iannucci raises job awareness:
If you’ve ever had to implement Change Data Capture (CDC) for a database in an Availability Group, then you know that the CDC jobs don’t really consider the Availability Group. The capture and cleanup jobs created are set up as if the database exists only on a single instance.
And that’s a problem, because I would guess quite lot of databases are in Availability Groups. Maybe even some of yours. If you have this issue, I’ve put together a step-by-step solution in this post.
