On top of what Vipal suggested, the issue may be due to a signature mismatch between the version you have installed on the device and the one that Play Store would deliver (this is a common issue if you try to test it with debug builds). See https://developer.android.com/guide/playcore/in-app-updates#troubleshoot

Recently the Play Core API started returning an API_NOT_AVAILABLE error if the app is not owned by the user or the signatures mismatch, while before it used to return a successful UPDATE_NOT_AVAILABLE Task.

The recommendation is:

• if you use the Kotlin Extension, make sure that you are catching the exception thrown by requestAppUpdateInfo
• if you use PlayCore Java, make sure you have an onFailureListener that handles failures from getAppUpdateInfo
• in order to test a debug build, you can use Internal App Sharing, as explained here: https://developer.android.com/guide/playcore/in-app-updates#internal-app-sharing
