Huawei p 10 lite background?

So I would like to have a slideshow as a lock screen background, but it does not work. It remains only the set image for both backgrounds.

The slideshow does not refer to the fact that the image changes every 3 seconds, but when you turn it back on, a new image appears, if you make a phone call then the image looks different than before.

What you imagine there would be so much energy that you would constantly whine, your battery is empty.
