IAP Why google play refuse my release ?

Hello, I got this e-mail from google :

"Violation reason
App issues
Your app uses the Unity SDK. This SDK collects persistent identifiers, including Android IDs and Advertising IDs. Persistent device identifiers must not be linked to other personal and sensitive information or resettable device identifiers.

Please consider migrating to another SDK or removing the relevant SDK. Also consider upgrading to a policy-compliant version of the SDK that does not contain the offending code, if available from the SDK provider.

According to the information provided by your SDK provider, you may consider upgrading to 4.0.1. Please consult the SDK provider for further information.

Affected versions:
App Bundle:6, App Bundle:6"

I think IAP is the cause. Idk what to do to solve this problem is anyone can do something for me ?
