Which Unity version do you use? Do you overwrite gradle templates in your project? If you do, you might have specified to disable signature version 2 in the gradle temple, which would cause this. Do you also use the same app to target oculus devices? If you are targeting Oculus Go or Oculus Go + Oculus Quest, then your project is configured to intentionally disable signature version 2 as that is required on those devices.
Generally the Amazon Appstore is directed to Amazon devices like the Kindle and Fire tablets. For a Pixel device, you would probably want to publish to Google Play. Is there a specific reason you are using the Amazon Appstore on this device? https://www.cnet.com/how-to/how-to-install-amazon-appstore-on-your-android-device/
