Hey @firebombmarkus, thanks for flagging this to us. As per the last update from our Farm Heroes CM, @MarkHawk: "The Studio are aware that there's currently an issue for mobile devices. We will soon release an update to Farm Heroes in order to solve the loading issue. I suggest you keep an eye out for the updated game on your app store here over the next couple of days".
I'd suggest that you keep an eye on this thread for future update
