How is it working for you?
For me it is extremely unstable. The game has trouble starting, Once you get in it can behave as expected then suddenly it freezes. I might get good behavior for 10 minutes and other times it freezes instantly. I’ll frequently get a freeze as soon as I enter chat.
The other behavior instead of freezing is the graphics slow way down. I hope this is all fixed before iOS v12 is generally available.
