A. Check the app's settings to see if there is an option to upload songs. Some apps may require you to enable specific permissions to access your music library. If the upload feature is not available, consider using a different app that supports song uploads or allows you to import music from your library.

B. Ensure that the app is updated to the latest version, as new features may be added in updates. If the upload feature is still missing, consider reaching out to user forums for potential workarounds.
