Something strange is happening currently in one of the apps i'm developing.
While developing the APNS Pushtoken could be obtained properly. As soon as I pushed the app for testflight internal testing it doesn't work anymore.
The well-known error is throwed: 'APNS Push token - No valid aps-environement-entitlement whatever could be found'
I usually solved this error through refreshing all the mobile provisioning profiles in XCode, but this doesn't work in that case.
The App ID is configured properly for push notifications production and development.
Any Ideas? Would really be glad.
The problem was that the provisioning profile was created before adding the Push Notifications to the App ID. Creating a new Provisioning Profile and download it through XCode solved it.
