Empty cards after language change

problem at mobile devices (IPhone/IPad with currently newest software update):

After I changed my language from german to english, all cards are displayed empty.
Without a name or description.

What can I do? A re-installation of hearthstone makes no difference.
Is there a way to manually trigger the download of text data?
