App Preview Portal not working

Hi, since yesterday my app preview portal has not been working. When I go to the “Launch” tab and press “Open App Preview Portal” nothing happens. To make sure it wasn’t a problem with that app I created another app with only the default components (title and paragraph) and it still wasn’t working. No APIs or variables in the new app. Any ideas on what could be wrong/how to fix it?


There’s a bug in that button, we’re fixing it asap! In the meanwhile you can access the preview at

Thanks for the help!
