Xperia Z3 Dual, lost flight mode icon!

[akaii]

When I switch between users, from main user to another user on my phone the flight mode icon is lost from expanding notification bar(or quick settings bar; beside WiFi and Bluetooth icon).
I need to restart the device to get it back.
My device: Xperia Z3 Dual, Android Lollipop 5.1.1 .

Have you tried to tap on done then check again?

Tap on what?

[_alexdon_ · Accepted solution]

On Done, after switching to other account.

Tnx alex!
After switching, I expand again users list from status bar and tap on done. The problem is solved.
(it appears like a bug not trick!)
But thanks again @alexdon💐
