How do I reinstall or update the app on the target device to fix a persistent issue?

If the app is not functioning correctly, support may provide a new build link. To update without uninstalling: 1. Download the new APK using the link provided by support. 2. Open the downloaded file to install — this will update the existing app. 3. Do not uninstall the app before updating unless specifically instructed by support. After updating, apply any recommended battery and permission settings for the app to function properly.
