Hello @nechtas
Starting with Billing Client 5, only offers for which the user is eligible for are returned by the API. This means if you have already previously enjoyed an introductory offer, it will not be returned by the API and hence we cannot fill the introductoryPrice field. In BC4, offers were always returned even if the user was not eligible.
Unfortunately there is no way to "reset" intro offer eligibility in Android, so if you want to test it you will need to create a new Google testing account.
