I am using FCM for push notification.

{
"to": "ffHjl2CblrI...",
"data": {
    "message": "Offer!",
    "image": "https://media.giphy.com/media/l4lR0Q5u91kTNJPsA/giphy.gif",
    "url": custom url,
    "mediaType": "gif",
    "type": "notification type"
},
"notification": {
    "body": "Body",
    "sound": "default",
    "title": "Title"
},
"content_available": true,
"mutable_content": true
}

This is my payload content.

I am using NotificationExtension above code which I am using to download data from push notification.

I got a success response from developer certificate. If I check with production certificate(update with previous one) I got error like this

__NSCFLocalDownloadFile: error 2 creating temp file: /private/var/mobile/Containers/Data/PluginKitPlugin/7D6B57B4-DC4D-4F3E-8113-C8469BA66BBB/tmp/CFNetworkDownload_NQQfGi.tmp

If I delete the app and run again it's working. But if I update version with new IPA it doesn't show the image in the notification.

What I miss, Is that certificate issue? Is app permission issue?

I am using separate APP ID (without push notification config) for UNNotificationServiceExtension.

Update

Also checked with APNS to that too not working.

Few more code and explanation about APNS and payload content

  1. Richmedia notification notification not working in production certifcate

  2. Rich push notification not work properlly after update IPA (same IPA with overwirtten)

I have encountered this error, which belongs to PESIXErrorDomain and I'm pretty sure it's a iOS bug probably introduced in iOS 10 along with other bugs.

The workaround I have implemented is to invalidate current session, start a new session and start a new download task with new session with acquired resume data.
