Hello fellow meteorites 
I would like to ask for your help on the following issue I face.
We have an app in production with backend server, and building Android and iOS mobile FE.
The issue I’m having is that if I ‘run’ my app in iOS with ‘–production’ flag, it launches but it won’t get past the splash-screen.
meteor run ios-device --mobile-server https://<my-server> --production
If I don’t minify, the app runs normally
meteor run ios-device --mobile-server https://<my-server>
The server is already pre-built and serving from a different host.
Running on ‘android-device’ with or without --production option works like a charm…
My XCode console logs when I run with --production option:

Some ‘information’ has been ‘covered’ for obvious reasons.
I can’t see any error in Network connections with Safari DevTools nor in the browser console.
Any ideas? I’m really stuck with this…
Thanks in advance
