CDN Cache Not Updating Collection Image

I’m actually noticing some caching issues with my page content as well. I made some text changes to one of my Page’s content. It’s now been over 48 hours and it’s still showing the old page content.

When I look at the page content within Shopify admin, I see my updates. However, the value assigned to ‘page.content’ is still pulling in the old data.

It would be great if Shopify gave us a way to flush our site cache. Otherwise, how can we request to have the cache - in what I’m guessing is due to the CDN - flushed?
