I'm working on web browser but I can't edit my Design screens

Currently, only screens which were created on desktop can be edited on desktop. 

If you created your screen using the Marvel iOS or Android app, you'll need to head back to the app to edit your screen. You can get help with this here

We're working on creating cross-platform compatibility which means in the future, you'll be able to edit screens anywhere regardless of where they were created.
