When you first launch Edge Animate Preview 7, you see a message that states, "The pre-release period for Edge will expire."
This message is expected. Adobe is offering Edge Animate as a free preview before its commercial release so that users can evaluate it and provide feedback. This feedback helps shape the features and roadmap of Edge Animate. Each preview that is released has an expiration date to encourage users to evaluate newer versions as they are released.
Edge Animate is no longer actively developed. To know more about Edge Animate end of development, see the Edge family of products | End of development.
