iOS: duplicate symbol error on build

[alexaround25]

I have followed all the steps, I have changed import in MFLReactNativePayPal.m from:
#import "RCTBridge.h" #import "RCTConvert.h"
to
#import "React/RCTBridge.h" #import "React/RCTConvert.h"

in order to work with React Native 0.54, but when I try to build the app I get the following type of errors:

duplicate symbol _OBJC_IVAR_$_PPRiskDeviceData._adId in:

ld: 1253 duplicate symbols for architecture arm64

Can you please tell us if the library is still maintained and working?

Thank you!
