IOS + admob (cloud fails, local works)

Couldn't find a recent thread that handles this issue specifically, so I've created one. If this is similar to some other thing let me know and I'll delete.

So unity cloud is failing the build with this errors:
29188: ❌; Undefined symbols for architecture armv7
29189: > Symbol: _CLURecordCustomException
29190: > Referenced from: _IOSImpl_CLURecordCustomException_m859661578 in Bulk_Assembly-CSharp_0.o
29191: ❌; ld: symbol(s) not found for architecture armv7
29192: ❌; clang: error: linker command failed with exit code 1 (use -v to see invocation)

Local build works.
I'm using unity 2017.4.26
Architecture is universal
Framework dependencies for admob files: only default, i haven't added anything new.
We have xcode 10.2.1 locally and using xcode 10.2 on cloud
Repository is svn
This is how my Plugins/IOS folder looks


Thanks for any kind of input!

LE: after more investigating, the issue seems to be coming from Fabric sdk.

LLE: after removing Fabric, we've stumbled on GameAnalytics with a similar error
> Symbol: _OBJC_CLASS_$_GameAnalytics
23927: > Referenced from: objc-class-ref in GameAnalyticsUnity.o

I think we're not selecting something really basic. Because it seems all plugins fail.

 

The GameAnalytics linker issue is resolved (somehow I've ignored GameAnalyticsUnity.a from repository).
The Fabric issue is still standing. It fails for all functions that call an external dll like:

Code (CSharp):

1. [DllImport("__Internal")]      
2. [DllImport("__Internal")]
3.        private static extern void CLURecordCustomException(string name, string reason, string stackTrace);
4.  

gives the error

Code (CSharp):

1. 29189: > Symbol: _CLURecordCustomException
2. 29190: > Referenced from: _IOSImpl_CLURecordCustomException_m859661578 in Bulk_Assembly-CSharp_0.o

For now I've removed fabric, but if you have any idea what could be the culprit it'd help.
