Apple introduced new privacy policy rules for mobile apps. Now developers have to go through huge questionnaire with complicated forms to fill out all the needed data.
The most important part is that you also have to do it for all third-parties your app has. The easies way to do it is to actually google "AppStore privacy policy THIRD_PARTY_NAME" and use related topics as how-to-dos.
It's pretty painful, but there is no other options rather than that, otherwise Apple might remove your app from AppStore.
Be patient and good luck! :)
The App Store is designed to be a safe and trusted place for users to discover apps created by talented developers around the world.
