What is the point of your response?  If Proseries offers a feature that we pay for, it should work properly or do not offer it.  More importantly, customer support should be able to resolve the issue.  I will say, Proseries has made improvements with customer support response time, but it is now lacking in quality, 2 reps were unable to resolve the issue.  

To answer your question, yes, my clients do review their year over year and it's a great tool for me to explain differences from prior year in a way they can easily understand, which is what they pay me for!  I do not get paid to just churn numbers into a return, that's what Turbo Tax is for.
