Moving apps on Huawei P8 lite 2017 from internal memory to SD card?

I'm aware that this question has already been dealt with here. Unfortunately, it does not work for me, or rather the smartphone of my daughter anyway. Any search on the net in the relevant forums could not lead to the goal.

My problem: The internal memory (16 GB) on the device is almost full. So we used a 32 GB SD card and moved pictures and so on. Now we would like to move apps such as Snapchat and various games on just this card. Unfortunately, this option, under Settings, is not available.

See picture attached. Does anyone know of you may remedy?

It's easy to explain: there are simply apps that you can't move and other apps that you can move. It's annoying when you can't move a big app, but that's just it, there's nothing you can do… 😉 I hope I could help you…

Ps: Try everything that moves, no matter how small
