Ctrl + F doesn't seem to be working to find things in large Modern View reports. Also, in aging summary reports, clicking on the total in classic view allowed you to drill down into an aging detail report, but modern doesn't do anything when you click on the total. Finally, in Classic view, when I want to highlight to copy/paste the entire report, I can always scroll from the top of the report and highlight all. In Modern View, the scroll stops when trying to highlight, so I can only highlight whatever is showing.
