I have bought the expansion today.
Somehow it doesn't show up in my order history and also not in the game.
I am logged in to the right account (on Google Play and my phone).
I did pay €4.
Does somebody know a solution?
You may have to exit (fully) the game and restart the app fresh. Try it. Let me know if it worked. A restart of your phone will guarantee proper shutdown of the app.
Thanks for the response.
I did what you recommended, but it unfortunately didn't work.
The weird thing is is that it doesn't show up in my order history on Google play.
