Why are my app settings not appearing in the Settings app?

Solution 1:

I experienced this issue for the first time this morning, on iOS 10.3. To fix, I simply opened multitasking view (double-click Home), and ejected the Settings app. Upon reopening it, app settings returned beneath TV Provider.

I’m quite surprised at the number of bugs with the Settings app since iOS 10 (another would be the disappearing navigation arrow in the upper-left).

Solution 2:

I am a iOS developer, and I just ran into this in an app I'm building.

From what I can tell, the application is only added to the setting app if

1. The app developer adds an additional set of files to the app called the settings.bundle which ops into listing the app in the settings app. If the developer has done this the app will be added to your settings app, when the app is installed on your device.
2. Or if the user grants the application permissions that are listed under app settings (this includes things like location permissions, or notification permissions). In this case the app will not be listed in the settings app until one of these permissions is granted by the user.

By default the app will not be listed in the settings app by default. If you want to have it added to your settings app, try granting it permissions to send you push notification, or access your location.

There is an issue where, if you've denied the app permission to use these features, the app may not be able to ask you to give it permission again, and you will not be able to access it's permissions via the settings app to grant the app permission to use these features. In this case you will need to delete the app from your device and re install it in order for the app to be able to ask you to grant it permission.
