Expired OneSignal Push Certificate for iOS? Here’s How to Renew It Quickly and Easily

Log in to the OneSignal dashboard and choose the app you wish to renew the certificate for.
In the App Settings, locate the “Apple Push Notification Service (APNS)” section, and hit the “Renew Certificate” button.
Follow the instructions to generate a new certificate signing request (CSR) on the Apple Developer Center.
Download the renewed certificate to your computer and import it into the Keychain Access app on your Mac.
Double-click on the certificate and under the “Trust” section, select “Always Trust” for “When using this certificate”.
Exit the Keychain Access app and return to the OneSignal dashboard.
Click on the “Upload Certificate” button, select the renewed certificate from your computer and hit “Save” to update the certificate within the app.
For compatibility reasons, it’s also smart to regularly update the WebViewGold wrapper portion of your app, although this typically does not need to be done simultaneously with renewing OneSignal certificates.
