Hello everybody.
I work on an iOS mobile App for kids, recently we uploaded a new app version to publish it on the Apple Store, but after the submission we received a message from Apple review team about new guidelines with analytics since early March which said :
We noticed that your Kids Category app includes analytics, advertising and collects, transmits, or has the ability to share personal information or device information with third parties.
Your app includes the following feature(s), contrary to guideline 1.3 of the App Store Review Guidelines:
Third-party analytics or third-party advertising with the ability to collect, transmit or share identifiable information, including, for example, IDFA. 
Next Steps
To resolve this issue, please remove this functionality or revise your app so that no personally identifiable information or device information is sent to third parties.
Our Analytics tools in the app are :
Fabric (Analytics / deeplinks / remoteConfig) and Crashlytics for Crash monitoring.
Today we can't launch a new release with these tools, and it's a problem for us.
Have you already dealt with this issue?
How can we be good with Apple review and use this tools for our app or if there is any alternatives.
Thanks for your help.
