How to make Apple Push Notifications work in TestFlight builds,Push Notifications won't work in TestFlight builds
Hello,
I'd like to know if anyone has problems testing Apple Push Notifications with TestFlight builds.
I've followed "Push Notifications basics" and "Push Notifications for iOS" tutorials, and I can successfully send push notifications from the PlayFab dashboard to a specific user who has a direct XCode build.
So this means that certificates are ok (sandbox), user registration is ok (they send to PlayFab sandbox tokens, if I trust the player profile in PlayFab). As far as I know, this is the only difference: a device with a XCode build will receive push notifications, a TestFlight one will not...
Can anyone help me troubleshoot this please?

I'm not familiar with iOS development, but after I searched, I got some results that might help you.
When you install via Xcode directly such as you are testing a development build in house. The certificate came from the sandbox environment, you need to send the push notifications through the development URL and provider a development certificate generated (or an authentication token), and you can't send it to the production push service.
Similar to this, Anything installed via TestFlight or App Store needs to be sent through the production URL and provider a production certificate generated (or an authentication token). And if you do send a device certificate to the wrong environment, the push service will see that as an invalid certificate and discard the notification.

Besides, this is not a Playfab-side issue hence you can get more help from Apple Developer Forums.
Thanks you very much. I changed the .pem pushed to PlayFab for a production one. This solved my issue with TestFlight builds. I mistakenly thought device tokens had a "sandbox" in their string, but this was part of the URL used to send the notifications (due to the sandbox .pem uploaded to PlayFab).
On a side note, I used Fastlane to produce and download the .pem file, but apparently it won't produce a file other than sandbox, even with a "--production" option. Bug? I don't know yet, but I had to do it the old way, on the Apple developer portal.
