I set you on situation:
I had a project 1.8.10 Objective C App that was without Fabric Crashlytics. So, when I got control of the project they told me that Fabric was already installed. I checked and yes, everything was good. Still, we updated the app to the 1.9.10 (totally different build number) and we set the itunnes connect deployment in 7 days. At first I believed that was something of Apple, but now we are in 100% and there's no data. Actually, I can't see my new app's version (1.9.10) in Fabric's dashboard.
(https://stackoverflow.com/a/41160905/9684719) Yes: I have checked missing dYSIM, runscript, plist, at Debug information in my project I have DWARF with dSYM File.
Crashlytics not reporting crash in Release mode Yes: I have my Fabric instantiation in Apps Delegate fine too.
Fabric doesn't update my latest build version I can see in Itunes Connect that there is people using my app.
