When you click on Reporting and get a list of reports, you easily get the impression that you can click through on any one of the columns and it will take you to that place directly. For instance if you click on "Bounces" within a report row, you expect it to take you to the list of bounces, because there are other places in the report where you can do that. I even think that in the past you could do that in reports. If you can make it work that way it would be an improvement. If you can't, you should at least have a color background across the row display on mouseover, that would suggest the columns cannot be accessed directly.
Hello - Happy to say that the fix for this issue was applied this morning. All metrics on the reporting page should be linked to their proper report, instead of defaulting to the Sent report for all. Sorry for the trouble.
Special thanks to @JulieL34 for reporting the issue originally!
