I have got the TicTacToe example to run and work, except that the push notification isn't always delivered. I haven't found any rules to when it works and not.
Also registering a new user seems not to work always. It often says "User creation failed" but then all of a sudden it works.
I am running in emulators and on one device.
How trustworthy are these services?I expected it to be production ready, so I was a bit surprised about this.
