Hi there, uploading a new APP on the play store i got this notification:
I have build a signed AAB file instead the .APK because i got an error uploading the APK so i need to use App Bundle.

How to update your client to API version 3?
Migration guide here looks like arabic for me.

Here an email from google Google Play Developer Support

We checked into the alert you are seeing: "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." in the Play Console regarding the API. Please note we have confirmed that these alerts are being sent out to developers who are either using an old version of the API or have a third party plugin using an old version of the API. If your app does have a API associated, please make sure to update it before the deadline; you can follow the steps here: https://android-developers.googleblog.com/2019/03/changes-to-google-play-developer-api.html

If you are using a third party plugin, please try updating the plugin to fix this issue. We do apologize again for any inconvenience this may cause and hope this information helps. Please note we do place a high value on developer feedback, and I’ll be sure to pass along your specific feedback to our product team.

Can you fix it?
Thank you!
