No, you don't need to uninstall the previous version. The app is designed to update automatically every few weeks. However, if auto-downloads are disabled on your device, you can manually check for updates in the app store.
To manually update:
- Open your device's app store (e.g., Google Play Store, Apple App Store).
- Search for the app name.
- If an update is available, you will see an option to update the app.
Keeping your app updated ensures you have the latest features and security improvements.
