Hello, so that`s it, when I click “publish”, nothing happens, it appears the loading icon for a moment and then it turns back to “publish”. Does someone know why this happens? Is there something I’m skipping or what? I can’t find information on what would prevent me from publishing the app.
Thank you!

I’m not experiencing this. Did you try after clearing your browser cache?
That’s because you turned on the “Publish manually” button. Normally just turn this button off, unless you want your changes not to be updated automatically. Publishing is basically after you create a URL that is shared with your users.
Changed this to Ask for Help because it doesn’t seem to be a bug.
