Just been looking at the Microsoft developer center and I checked the "Health" of a recently released application. Unfortunately it's not a nice sight with around 800 crashes in the last 30 days. What's even worse is 95% of these crashes are marked as "Unknown" with no stack trace or any information to help with sorting out the issue. See screenshot below:
What can I do about this, I need more information to try and fix any crashes there are in the app?
