The following updates have recently been made in the Appstore submission process and docs.
|Sept 28, 2020||Mexico was added to the list of marketplaces where you can specify a currency for paid apps. However, Mexico does not yet support paid apps or apps with IAP items. (Any app with the IAP SDK will be blocked in Mexico — only free apps are available in the Mexico marketplace.) More details about support for Mexico appear in a note in the Charging For Your Apps section on Step 3: Add Availability & Pricing.|
|Aug 28, 2020||Added a Firebase Alternatives section in "Migrating An Existing App to the Amazon Appstore." This section provides Firebase alternatives, equivalents, or other options when migrating your app over to Amazon.|
Note: Previous release notes were published as posts on the Amazon Appstore blog (with an Announcements tag).
