Hi, I have this message in the google play console:
We've detected that your app is using an old version of the Google Play Developer API. From December 1 2019, versions 1 and 2 of this API will no longer be available. Update to version 3 before this date. Note that this is not related to the AIDL/Billing Library deprecation.

unity says it is surely something related to the baas we are using. so I am asking here.
if braincloud still use the version 1 or 2 of the Google Play Developer API.
thanks
