Problem parsing the package
Check the system: Fire OS 6 or later, without Vega OS. If your device meets this requirement, download the TV APK again using the official link.
App not installed
Check the available storage and Fire OS version, then download the official APK again. Do not uninstall Mango: keep your data and contact support if the error continues.
Download failed
Check the code 5733121 and your Internet connection, then try again. If it still fails, give support the exact message.
Check compatibility
Fire OS 5, including 5.2.9.5, and devices running Vega OS are not supported by this APK. Check the system in About.
