Unity Engine

Our team upgraded to Unity 5.5 and now our app is having huge problems.

First problem was we noticed logging info Facebook took over a minute when it normally takes under a second.

Then, when we try to perform an action in the game it just crashes.

This does not happen in the editor.

Anyone else seeing lots of crashes with Unity 5.5?

After a day of debugging we narrowed it down. This happens when starting location services.
