Мое приложение нарушает правила в отношении рекламных идентификаторов Android

Команда Google Play отклонила мое приложение по следующим причинам:

The advertising identifier must not be connected to personally-identifiable information or associated with any persistent device identifier (for example: SSAID, MAC address, IMEI, etc.) without explicit consent of the user.

For example, we have identified that your app's attribution SDK enables collection of IMEI from devices which have an Android advertising ID without prominent disclosure, which is a violation of our Android Advertising ID policy.

Я не собираю IMEI явно, поэтому доступ к IMEI должен осуществляться одной из зависимостей приложения.

Как я мог определить, какой из них обращается к IMEI?

Обновлено: Это мои зависимости
