Hello Magic Soda,
I have not been able to see any issue that you mentioned on my iPad. However, we found that using the chat led to constant pop-up of the keyboard which made the platform close to unusable. The bug has probably been there for a long while. We are happy to have fixed it.
As for your concerns, can you be a little bit more specific as to what games freeze exactly and when? Does reloading the page not help?
Nicolas.
