Lumia Storyteller doesn't show up

[Vincentius Dalton]

I use Lumia 625 with Windows Phone 8.1.1 + Lumia Cyan. I just installed Lumia Storyteller from Store. After installing it, the Store says that the app has been installed, however it doesn't appear in the app list. Not even in Storage Sense (I've checked both in phone and in SD card). Now I can't even "uninstall" it.

What happens? How to solve this? Thank you.
