I have created the certs already. Not sure what it means by suitable provisioning profile for service extension. The tool requires me to rename it to something ".mobileprovision". Notification certificate has ".cer" extension. can someone share some light on this?
Here is the error.
Error: couldn't find a suitable provisioning profile for the "OneSignalNotificationServiceExtension" App Extension.
App Extensions require a dedicated provisioning profile, different than the one used to sign your apps. Please put this provisioning profile alongside the one for your app and name it "MyGame_Dev-AppEx.mobileprovision".
You don't need to change your signing identity. The builder will simply pick the "C:\Users\sats\iOS Project Builder for Unity\Keychain\MyGame_Dev.mobileprovision" profile for your app, and "MyGame_Dev-AppEx.mobileprovision" for your app extension.
Once this is done, you can build your app again.
