App store app only works when the app has never been installed on the device

[JulPol]

Hi all,

I'm having a rather strange issue with an app which I recently published to the app store. The app uses location services and web services on startup as well as requesting to use the users push id.

- When the app is downloaded from the app store for the first time on a device it works fully.

- When the app is deleted and redownloaded from the app store, it continuously loads the json content. It does not crash and allows me to click around the app, but never loads the json content.

- If a user has the app on their device and they go to install an update I have released then it all works fine.

- Any replications of this with apps installed via Xcode as either debug or ad-hoc distributions always work without fail.

- The problem is OS independent.

- The problem is network/network conditions independent.

If anybody can help with this issue it would be much appreciated. I have scoured the web for ways to debug apps which are on the app store but with no success as of yet. Although I'm pretty sure that there is no way to do this.

Thanks in advance.

Well you could use flurry to catch any error and log them, this should give you some information.

The weird thing is that it looks like some app data still lives on the phone after the app is delete.
Are you using any kind on caching on the JSON data?
Is CoreData used to store data, I've seen some weird thing with backups and coredata.
