Your browser was unable to load some necessary resources, contact your IT network administrator and ask him or her to allow access to [lists cloudfront.net URLs]
This error appears on all app editors. I filed a bug report and contacted support via email. Must get this resolved ASAP which is the only reasoning for multiple contact attempts @emmanuel @josh Thank you.
Update: I followed instructions based on similar errors other people have had with Cloudfront such as clearing cache in browser, flushing DNS cache via command prompt, attempted access on 2nd computer and alternate browser on same computer and separate networks. None of these have had an impact.
Update 2: Heard back from Josh, looks like a Cloudfront issue and not related to Bubble services. Thanks for the quick reply guys!
