If you currently have the previous version of the app on your mobile device, simply update the app through your respective app store. See below for details:
iOS devices – Apple App Store
You can check to see if the iPhone app has updated by simply opening the iTunes App Store on your iPhone or iPad, and tap the Updates icon at the bottom of the screen. If the app needs updating, it appears with an Update button next to it. Tap the Update button to update the app. If more than one app needs updating, you can update them all at once by tapping the Update All button at the bottom of the screen.
To turn on automatic updates
- Tap Settings > iTunes & App Store.
- If you’re not already, sign in with your Apple ID.
- Turn on the content that you want to automatically download.
You can turn Automatic Downloads on or off over your cellular network on an iPhone or iPad Wi-Fi + Cellular. Go to Settings > iTunes & App Store and turn Use Cellular Data on or off. Cellular Data downloads are limited to a file size of 100 MB or smaller.
Android devices – Google Play
If you don’t want to look into every app update and would rather things work behind the scenes, you can set your Play Store app to automatically update apps on its own. This is done through the Play Store settings.
Open the Play Store app on your Android and slide out the left menu. Open the settings, and look for the entry labeled “Auto-update apps.” Tap on it, and you’ll have the choice to update apps over Wifi only, update apps over any connection (this might use lots of data) or to turn off automatic updates. Choose the setting that works best for you.
