Embedded app sandboxed despite correct headers and App Bridge initialization

Hey @Rudolph_94 - thanks for following up. I was able to get some more info on this for you. One of our devs mentioned a bit of this here:

Blocked script execution in <URL> because the document's frame is sandboxed and the 'allow-scripts' permission is not set

This error fundamentally cannot block your app’s CSS when your app is actually loaded (to be shown on screen). What’s happening here is that we use a sandboxed iframe to preload your app before loading it for real in a different iframe. The preloading sandbox iframe intentionally prevents JS from loading (which results in those “errors” in your console), but that frame is never shown on screen. It is removed the moment your app begins loading for real. Your app is loaded in a totally separate …

We’ve spoken with the app review team and the error there shouldn’t affect your app’s status. If you do see any other issues pop up though, feel free to reach out to me here and I can look into things for you.
