Change the encryption key of the .AAB file to publish it to the Play S

When I try to publish the watch face on the Play Store, I get the following error message…

Does anyone know how to change the encryption key, so that it matches that of Google Play, and be able to publish the sphere in the Play Store.

@MKC

Are you trying to update a current watch face or is this a new one? If this is updating you need to contact Play Store support for instructions.

If a new app
Be sure you are using a valid password and that the location is filled in.

A valid password can contain 6 to 30 characters, begin with an alphabetic character, and use only alphanumeric characters and special characters like Underscore (_), Dollar ($), Pound (#). The password must contain at least one number.

If none of this is of use then ask the play store for assistance.
