So we develop several apps for Android.
And since the whole company is full of .Net developers we´re using Xamarin.
That piece of software alone is worth more than one rant.

But today someone called and said he updated to the latest version he got from our server.
But now one of the menu points in the settings menu is opening the wrong mask.

I´m like ... what? Who fucked that one up now. Ok...
I look at the code and, I didn´t expect it to be honest, but it looks alright.
The menu point has the correct id. The function "OnOptionsItemSelected" looks for the correct id and opens the correct activity.
Just to be sure I also check the activity.
Everything good.

So I start up an emulator. Deploy the app in debug. Works correctly.
Create a self signed apk and install it on the emulator. Works.
Repeat the same with a tablet and my personal phone. It works.

Then I install the apk from the server and would you look at that.
It opens the wrong mask.

So it seems only if the app is compiled on the release server it shows that strange behaviour.

And for the love of my 1080ti I can´t figure out what causes it...

Thank you Xamarin!
