This is the Xamarin Issue which causes the problem. Apparently work in progress:

Thanks for the post. I'm glad to hear you were able to get this working again.
I'm not sure I follow this totally though, so just to be clear, are you saying there is a bug in the official Dropbox .NET SDK v4.8.0, or does the bug only appear to be in the "Xamarin Forms upgrade, .net and PCL stuff" ?

Thanks, Greg-DB It is difficult to blame the Dropbox .NET SDK v4.8.0. I need to upgrade the Dropbox SDK only and see if the problem persists. I will update this thread accordingly. Unfortunately, this may take a while before I get the time to do this.

@xtremebytes I ran into the exact same issue.
My investigations:
Just downgrading to Xamarin.Forms 2.5.1 resolved the issue for me. I kept the newer version of the dropbox sdk and the .NET standard stuff. The issue only exists on iOS, Android and UWP still work fine without downgrading.
So it seems the problem occured in the Xamarin.Forms iOS stack while switching from Forms 2.5.1 to 3.0 or 3.1-Pre1.
