Undefined symbols for architecture armv7

Hi,
We're trying to build a mobile game on iOS using Unity Cloud Build and we're getting the following errors:

Code (CSharp):

1.  
2. 2549: ▸ ⚠;️  /BUILD_PATH/com.cgames.dist-ios/temp.XXXXXX20190725-4049-cpedm3/Libraries/Plugins/iOS/AppsFlyerAppController.mm:31:142: conflicting parameter types in implementation of 'application:continueUserActivity:restorationHandler:': 'void (^ _Nonnull __strong)(NSArray<id<UIUserActivityRestoring>> * _Nullable __strong)' vs 'void (^__strong _Nonnull)(NSArray *__strong)' [-Wmismatched-parameter-types]

We hope someone would be able to assist.

 

I'm running into this as well, did you manage to solve it? Thanks!

 

My project had same error and I remove an aseet for solving it.
This is just my guess.
It need to set "Other Linker Flags" on XCode.
I used this asset and it need such setup.

Maybe you can set the value by like meta file but I couldn't find that way.
I hope for solving it!
