Installed Apps not showing in Cellular Allow Data for section

Those apps appears in that section when i turn the data on and use some apps from the data. Each app when takes the data connection and use it start appearing in the section. Once it appears in that section i was able to remove it from there.

i had the same solution as the writer before me. The "mobile data" part of your phone doesnt know app's exists until you use mobile data on them... IE I had downloaded snapchat using wifi and had my phone in airplane mode... i didnt use mobile data for snapchat and so snapchat never showed up in the list of apps that you can turn mobile data on and off for... as soon as i was out of wifi range and used snapchat, the app showed up and I could turn the mobile data off...

Here's some steps you can use to try to fix this. Credit goes here:

• Confirm cellular data is enabled by going to Settings > Cellular > Cellular Data
• Try turning Airplane mode on and off again by going to Settings > Airplane Mode
• Go to Settings > General > Restrictions > Cellular Data Use, make sure “Don’t Allow Changes” is toggled off, then tap Settings > Cellular, then turn Cellular Data to OFF, wait a few seconds, then turn Cellular Data back to ON
• Reset Network Settings by going to Settings > General > Reset > Reset Network Settings
• Reboot your device.
• Uninstall and install any problem app.

If nothing above helps you, you could try this:

• Back up your device (Settings > iCloud > Backup > Back Up Now)
• You can see your recent back ups by going to Settings > iCloud > Storage > Manage Storage
• Restore your device. Important this will erase everything. This is why you should back up first.
• Connect your device to your computer. In iTunes, select your device, and click Restore. Your device will restart. Simply follow the setup assistant and set it up as NEW, don’t set up from a backup because it is highly likely that this problem is due to corrupt information, this means that problem will repeat if you restore from a backup. We will restore your device from iCloud later.
• Now verify that the problem is resolved
• After verifying, now restore your iCloud backup. To do this, go to Settings > General > Reset > Erase all content and settings.
• When your device restarts, tap Restore from a Backup.
