We received a Mail from Google Play:
Hello Google Play Developer,
In light of changes to EU consumer laws, we would like to inform you about important changes to prices and promotions on Google Play for users based in the European Union.
Disclosing personalized pricing
We’ve added an API to the Google Play Billing Library that will inform users in Google Play’s purchase flow that an item’s price has been personalized using automated decision-making. Please reference Art. 6 (1) (ea) of the Consumer Rights Directive to determine if the price you are offering to users is personalized. To inform Google Play of when to add this disclosure you must have the latest version of the Google Play Billing Library (v.5.0) and call setIsOfferPersonalized() method the when an item’s price has been personalized for the user.
We checked the Documentation:
There is no option to call the method setIsOfferPersonalized()
