I had install iOS10 and i don't like siri suggested app, so i had turn it off according to this, but it didn't work. It still shows on notification center. I tried restarting it as well but nothing. Is there any other way around?
On the Notification screen, scroll to the bottom and tap
On the list of apps, tap the red circle next to
Siri App Suggestions, then tap
On the top right of the screen, tap
This should remove Siri App Suggestions from Notification screen immediately, no need to reboot.
Maybe you did not do it properly. I found a guide on Google that may help you: How to remove Siri suggestions
