Ionic push, TestFlight not working

Hi all,

I’m really confused right now, I’ve develop an IOS app with push notifications , in development push works like a charm, but when I put the app on TestFlight, push does not working at all. CURL return this when I’ll ask for my push status :

{“meta”: {“request_id”: “34046d2f-764a-4164-c1bd-b0c70ba5aae1”, “version”: “2.0.0-beta.0”, “status”: 200}, “data”: []}

My security profile is a production profile with APNS production certificate, and distribution certificate/provisioning profiles.

So what should I do ?

Thank you in advance
