We've used push notifications for the occasional status update (to all users) in our app for a couple of years. Today, we wanted to send another, but nothing happened. When inspecting the certificate, it says it expired november 2nd. Great. When I go into the developer portal and "Certificates - All", I don't find my certificate anywhere. If I open the AppID to my app, it says "Push Notifications • Configurable", as if it was never configured. Is this correct? I would think it should say "Expired" instead of Configurable, and that the certificate would still exist under "Certificates"? Is this right, or could it be that someone revoked/deleted my Certificate?
So, my only option now is to click "Configure" push notification in my app's AppID, I guess. If I remember correctly, it is possible to make this work with existing installed apps (without having to release/update the app), if I create a new certificate the correct way, right? How did that work? If I click "Configure" and "Create Certificate", I get to the usual "create a CSR then upload it, then download the cert". Is it correct that if I use the same CSR as we used the previous time we created this certificate, get my new certificate, then give it to my server, I will be able to send notifications to existing devices?
