Hi, we noticed some issues with our app when it comes to receiving pushs sent when a device was offline. We know that only one push is stored if multiple are received while the device was offline but we got reports of multiple users that aren't receiving any pushs that were sent while they were offline. Reinstalling the App didn't help. We ruled out the third-party providers we used as my first thought was that there was some issues with setting the expiry but it also happens if directly sent over APNs. With a development build and the sandbox APNs I had no issue receiving one push after getting back online. But after reinstalling the production app no push after being offline. Example sent with the Push Notifications Console but I also tested it with curl directly: curl -v \ --header "authorization: bearer ${AUTHENTICATION_TOKEN}" \ --header "apns-topic: de.alarm-it-factory.ACC-App-Xamarin" \ --header "apns-push-type: alert" \ --header "apns-priority: 10" \ --header "apns-expiration: 1721379960" \ --data '{"aps":{"alert":{"title":"Test","body":"Expiry Test 4"}}}' \ --http2 https://api.push.apple.com:443/3/device/46F201D299F2B900CF3BF3096341116B9D5A69D103F2C0ACF18634823F73AB79 Sent: 15.
