Upgrade Your Mobile App
If your brand provides a custom mobile app, it’s always good to update your app to the latest version to take advantage of its latest features and bug fixes.
To update your app on your iPhone
Open the App Store.
Tap your profile icon at the top of the screen.
Scroll to see pending updates and release notes. Tap Update next to an app to update only that app, or tap Update All.
Never miss an update! You can also turn on or off automatic updates on your iPhone or iPad.
To update your app on your Android
Open the Google Play Store app.
At the top right, tap the profile icon.
Tap Manage apps & device. Apps with an update available are labeled "Update available."
Tap Update.
Never miss an update! You can also set your apps to update all Android apps automatically.
