Answer 1

Contrary to the usual promotional bruhaha made by Apple for a couple of years in a row for its Apple Business Chat Sandbox as a great tool for developers, this seems to be yet another of their software duds.

I don't think Apple sandbox page is gone.

You still have the documentation at https://developer.apple.com/documentation/businesschat/exploring_business_chat

And the current sandbox env link : https://idmsa.apple.com/IDMSWebAuth/login?isESAEnabled=false&appIdKey=e096fbe1d4b3913a4fa19b9f21a9ad4e58ab71dc3963c5b72a439fb539b6bea6&rv=2

You’ll need a device running iOS 11.3 or later to use the Business Chat Sandbox.

On your iOS device, sign in to Messages using your Apple ID. Go to Settings > Messages > Send & Receive > Apple ID.

Sign in to Business Chat Sandbox with the Apple ID you are using for Messages. A QR code appears the first time you log in.

Scan the QR code with the camera on your iOS device. Then follow the notification on the top to launch a Business Chat conversation with the Business Chat Sandbox.
