Apps created recently all will not launch

I can create and edit my apps and run them in the in-preview mode. However, when I try and access them via a web link, I am getting the error "The app didn't start correctly. Try refreshing your browser. If the app worked previously, try opening with a previous version of the web player." I get the same results in Chrome and Firefox. This has only been happening as of today on multiple apps.  I have even created an app saved it with nothing in it and got the same error. Please help this is extremely frustrating.

Re: Apps created recently all will not launch

Hi @Sphillips1 ,

This problem may be caused by a lot of reason.

Please try:

1) turn off "Experimental Performance Improvements" in advanced app settting and republish your app to mitigate this issue.


2)clean your browser's cache and update the browser to the latest version.


Here are some similar issues for your reference:


If the problem still exists, I suggest you open a ticket:
