We were building a site in Adobe Express pre update and now it appears there are a handful of issues with the application that make it completly nonfunctioning.
1. Font libraries are no longer available whihc changed everything that we were using for our project.
2. Preview and Presentation options no longer function and only show a blank screen.
3. Publication options menu is no longer part of the application. Basically you can build a site, you add collaborators but you cannot publish a site or use any of the custom URL featurtes that were originally available.
Long story short, the application is not function to publish previously or newly created pages. Are you aware of these bugs and will tehy be fixed soon.
