Answer 1

When you install your app on the device via XCode it will run in development (sandbox) configuration. You will receive development token and you need to issue push notification via ssl://gateway.sandbox.push.apple.com:2195 (using development certificate).

However: when you install your app via TestFlight your app is compiled (an run) in distribution (production) mode: production token is not the same as development token. It is also not enough to simply use this new (production) token. Push notification has to be issued via ssl://gateway.push.apple.com:2195 (using production certificate) in this case.
