I have noticed that when I press the CMS tab, it opens initially and I can update the existing collection item or add a new collection item. After closing CMS and returning to the main screen, when I then press CMS it does not expand to show the projects. Or… sometimes it shows the projects and I click on the project and Webflow just returns to the main page.
I have tried in Safari and Chrome on a Mac. I am assuming this has started since I joined the eCommerce beta.
