Amazon will close its app store for Android devices on August 20, after which users will not be able to access the platform or guarantee the functionality of previously downloaded apps. The app store will remain operational for devices running on Fire OS, such as Fire TV and Fire tablets. Additionally, Amazon's Appstore will be removed from the Microsoft Store on March 5, coinciding with the discontinuation of support for the Windows Subsystem for Android. Users are advised to cancel app subscriptions and seek alternatives like Google's Play Store and others. Amazon Coins will also be discontinued on August 20, but users can use existing Coins until then, with refunds for any unused Coins to be provided later.
