Can I change lockscreen wallpaper without Google Now Launcher in Nougat 7.0?

[AC Question]

I am currently using a Moto Z that updated to Nougat 7.0.
I noticed that I cannot not change lockscreen wallpaper by any method except Google Now Launcher.
I tried to change wallpeper (I use arrow launcher, but so did other method in wallpaper changing) as what I did in 6.0, however only home screen wallpeper can be changed while Lockscreen wallpaper remain unchanged.
Is Nougat designed to be so or a bug?
Is there anyway to solve it?

Moved from the Nougat forum to the Moto Z forum, because this kind of thing is more device-specific.

I use the stock launcher on my Z Force (Launcher 3 I believe it's called) and can change the main screen wallpaper and lock screen wallpaper independently. When selecting a new wallpaper I get the pop-up asking g if I want to change Lockscreen, Home screen or both. Not sure why it wouldn't work the same with the same for you?
