Hey !

Welcome on board the community ! Hope you’ll have a great time here. Have you tried to do a forced refresh (sign-out, close the browser, clear the cache) and only after that retry to publish the app again. If the problem persists you should definetly contact :

There has been a similar case recently where the user had some strange code in his app. Please let us know !

Is that the correct url?

Do you have visibility conditions on your tabs?
