Simcity buildit keeps crashing after update

Which iOS-Version?

I tried to buy some seasonal currency, which didn’t work, because it still said 15/15, then the game keeps crashing. I made sure there was plenty of memory free but it still does it and I have no idea how to fix it 

So funny, when I reported this in game they gave me the same useless steps told me that no one else was reporting problem and closed my ticket as resolved without resolution.
