This is to troubleshoot if push notifications are not working on IOS while they are working fine on Android.
Checkout this link first for push notifications are not working on Android app.
believing that your push notifications are working on Android, please check following to ensure they work for IOS
- Create auth keys(.p8 files) for push notification https://androapp.mobi/blog/create-apn-auth-keys-ios-push-notification/396 and upload them to your firebase project https://androapp.mobi/blog/upload-apn-auth-keys-firebase-project/402
- Check the bundle id used while creating app id and package name while creating firebase app for IOS
- if it is not the same, you need to create new firebase app with the bundle id used for app, update it in the account & settings tab, trigger an Android build (so that we get the new id at our server)
- send an email to us mentioning that you have changed firebase app id and would like to get the new app for the same.
