What I observed is loading takes time on all browsers. And sometimes loading is fine on firefox and sometimes not. Can you pl share your edge animate composition for us to have a look?
Sorry - dumb question - how do I share my composition? I created a zip file of the project, but I'm not sure how to upload it to Adobe Forums. Should I put it on dropbox and share the link?
You can upload to any sharing site (dropbox, creative cloud, and so on) and share the link with us.
