Please follow these steps to reinstall the app from the app store:
First uninstall the app, and long-press on the app icon for about two seconds. All the icons will start to wiggle, and you’ll see an X on the top left of the icon. Tap the X to delete it.
The second way to uninstall apps on iPhone was recently added in iOS 13. Open the App Store and tap on your profile picture in the upper right corner. This is where app updates appear. You can scroll down to see a list of apps that were recently updated. Swipe right on one of them and you’ll see a delete option.
