Trying to upload an instant game version to Manage hosted assets screen, getting a CORS error on the upload. Unable to test new versions on facebook. Go to Facebook Developers Apps > User Cases > Launch a game on Facebook > Web hosting > Manage hosted assets and upload a zip file and click Upload to reproduce.

When trying to display banner ads in an unpublished instant Game using the Javascript API, it always returns a 500 error (see attached screenshot). Apparently this has been the case for a week. This is making it impossible to develop Instant Games with monetization since you can't test with ads before publishing. Please fix ASAP.

Hello, guys!
We're trying to get advanced access for pages_messaging permission so that our Instant game could communicate with our players using messages (over pages, it's described here: https://developers.facebook.com/docs/games/engage/game-bots/)
We set everything up and checked from our side - messages work correctly (if messaging is available for user, they receive notification). It works perfectly for app admins and testers, if they are subscribed to the application page.
The problem is: we can't produce it on review, because connection between pages and test users is unavailable.
The only way to reproduce this for review team is using the account, that is already in application roles (admins/developers/testers). But our attempts to give them the credentials for such account or add review team representer to app roles are declined.
Please, give us the advice, how to pass this review!
