What steps will reproduce the problem? 1. Run the notification test client and sent notification to wrong device token 2. Run the Feedback test client you will see the nothing returned 3. Try again

What is the expected output? What do you see instead? Should it be return something about the previous send errors ?

What version of the product are you using? On what operating system? Windows 7

Please provide any additional information below. I haven't worked Feedback test client, it's returning allways 0.

I learned that Apple feedback service doesn't work on ad-hoc mode. Sorry, newermind this issue. Please close this issue.

Thank you

Let's not close this quite yet - I have the same "issue" and need to understand if it's user error/misunderstanding on my part or something more fundamental...

Can Feedback be tested in sandbox mode with a "real" app in development (not ad hoc distribution, but currently only in development)? If so, I assumed from reading the feedback docs that sending alerts to a valid device that had uninstalled my app would generate some feedback to tell me that the app was no longer installed. But I tested that scenario and still received no feedback. I also tested just having the app turn off all the notification options. My next test would the one above - bad device id, but that isn't a real-world scenario for me (users uninstalling an app would be).

Anybody have feedback working?

P.S. Maybe there is an "intelligent" timing factor involved? After uninstalling, testing and the later reinstalling my test app received the last of my test messages (after a significant delay). Does the APNS server have some threshold of failure before it generates feedback?

P.P.S. I think I've answered my own question. The Apple docs for the Feedback Service indicate that it requires "repeated failed delivery attempts" in order to generate feedback. So I probably have not created enough failures to warrant feedback notification. Actually makes perfect sense since a few failed attempts could be due to anything and taking action on intermittent failures would be bad. Thanks - this is a very useful tool.

@craigheartwell in apple's dev forums it was pointed out to me that you need at least 2 apps that support push to be running in the same apns mode (sandbox or production) in order for feedback to work. So what you would need to do to test sandbox feedback is create a second app with a different appid and leave it installed on the device after uninstalling your primary app for feedback to work. As it was explained to me, when the last push enabled app is removed from the device, the device NEVER contacts the APNS server ever again to save battery. This means that the device never reports to APNs that the app was removed and APNs can't send feedback for the app. We decided to just move to production to test feedback rather than build a second app for no reason. Hope that helps.

Great post @redisant

This makes sense, albeit a bit weird. Usually I just use production instead of sandbox anyways for testing apns and feedback. I've never had problems that way.
