I disagree: if you're a good product owner, it will aid with the goal of scaling.
For example, when you're sitting there walking them through something they could do alone, are you just playing back some script, or are you getting an understanding of where they went "aha!" and making note of how you can embed that aha moment into the product itself?
You’ve found me out! Not only is it excellent customer service, it’s also priceless market research that I would be lost without. Side conversations during calls like that have led to more improvements and features (and in one case an entirely new side product) than I can possibly count.
