[Smush Pro] cdn, yellow flagged items, Smush Pro trial

Hard to find specific answers for my issues, even though the general categories are in your documentation.
1) Any difference using your cdn link if I’m using Cloudfare currently?
2) I’m still getting the yellow flag on the right side saying I should match image sizes to the container sizes. But doesn’t Smush Pro do that? Also, HOW do I do that?There are no links to click for each of the 39 images lilsted?
3) Doesn’t Smush Pro trial allow us to chat?
4) I’ve run Pro several times and still get errors on GT matrix and Google Pagespeed saying I need to optimize images and serve in next-gen formats.
