Please provide me with the EXACT steps to reproduce the bug.
So as soon as you do that, and we have the steps we can prioritize a fix!
You mentioned that the Studio is crashing, but I need more info, what version are you using? 4.0 beta? what exact steps are you doing? can you a make video of the crash so we can see the process you take?
Let me add the the Ad engine is in beta, so it is expected to have bugs. We expect to push to final release in the next few weeks.
So please be sure to provide all that info...
Regards,
Sean.
