Blank screen with detached expo app with react-native-fbsdk

I detached my app and it worked fine, now i installed react-native-fbsdk and change quite a lot of MainActivity and MainApplication my app is getting stuck at blank screen. Expo XDE is running and build is successful. Should i change something in those two files to make it work again?

hmmm… it’s hard to say what made things break.
if you use git for version control, i would try git bisecting until you find the first change that made it break and then isolate the difference that way.
