1. I can confidently say that I speak for all of the ArcGIS Pro development team to thank you for wanting to help improve the software by reporting issues. It really is appreciated.
2. As I was a Technical Support analyst for a few years, and I currently still keep an eye on many things coming through Technical Support, I can vouch for what Thomas Colson shared - "if you write a good steps to repro, a case can be closed in a day. There are several good analysts, I've had a few take what I initially submitted and the first and only email I got was the bug confirmation."
Writing clear, numbered steps (yes, literally numbered) and pointing out what you think the bug is (was the bug step 3 or step 5?), will speed up the process. Including annotated screenshots pointing to exactly what you're talking about helps too. Or a video! Use tool names specifically. When you click a button, if you don't provide a screenshot, you'll need to describe exactly what button you clicked (e.g when you added data to the map, did you do it from the Add Data button on the ribbon, or did you right-click a feature class in the Catalog Pane to add it? To a Current Map? To a New Map? OR were you in the Catalog View and not the pane? Anyway, not to go overboard here, but just pointing out that submitting an issue REALLY quickly and painlessly, is only effective if another user can replicate what you're describing. If they can't, it will be necessary to get more information, and that will be hopefully through a call and screenshare as that will be the best way to get a full understanding; if the exchanges are done by email, I guarantee that the case will take longer).
Provide specific error numbers. The goal is to make the issue totally reproducible without the need for an analyst to call you for clarification.
There are current discussions happening around the Report Bug button on Contact Support page:
Obviously submitting a really well-written, reproducible bug will take some time, no matter how you slice it, which is why I started by preemptively thanking you and anybody else who takes the time to do so!
One other thing to remember before you put in the work would be to search the technical support site to see if you find an existing bug that describes what you're experiencing. If you do, now you just click Subscribe which not only sets you up for notifications, but also increments the count of users interested in that issue which helps in the prioritization process.
Hope this helps.
