Cooking Tale Support

I feel like I'm really struggling to pick up the items, even in the tutorial. Is it just me/my device, or do others get that feeling too? Are the developers still working to improve performance?

I don't have this problem, but I find that if I'm tapping too fast the waitress stalls as if she trying to catch up. This also causes the patrons to lose patience.

I'm starting to get this issue now Vivian ,past day or 2.  It takes me several clicks now on 1 item before it 'registers the action'

I don't know if this the right place to ask, but the star bar at the bottom on the level I am on is not working at all! I can't see my progress, I uninstalled the game for quite awhile and I come back and it still does not work! I even have a new phone!
