With Connect IQ Store version 2.12 on Android (I don't have an iPhone to test the iOS version) characters < > { } ( ) and | (there may be more) are removed from a string application setting upon saving, where with version 2.11 they weren't removed. In case a user upgraded from 2.11 to 2.12 and then tries to open the application settings page for an application that has one of the mentioned characters inside one of the settings, the following text is displayed: "Connection Error We had a problem loading settings for this device."
