Hi,
we’ve started to receive support tickets regarding black screen after startup from some of our users as well. We have several games out, and the users that report the error gets a black screen on all our Corona built games. It makes no difference if the game is built using a pre-graphics 2.0 or post graphics 2.0 build.
What’s the status on your side, Corona Labs? Our support team receives quite a lot of tickets regarding this, increasing every day.
