Sorry, that was me. I had changed a setting without realizing it would effect the "What's New" feature, changed it back last night. I don't know if there is a way to change it on your end but I will look and see.
Mine went from 25 to 100. Now it is back to 25. I prefer 25, but I can live with it either way. I did check personal settings and tried to change, but the system overrode the change.
