Hi, I just realized that for at least 10 times in a row I tried to use pagespeed insights and thought it wasn't working because the first thing that would show up was that "no data was found"... but later, a lot later, I realized that I just had to scroll down to see other data that was actually found.
I'm not an expert in UX, but I think this could be done better if the section without data was shorter and leaving space enough for me to see that there is more data ahead.
Hope it helps!
