Hey there nishan169,

Thanks for reaching out to the Apple Support Communities.

If having issues with a third-party app not working as expected, check out the steps listed in the following resource that can help: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

1. Close and reopen the app

Force the app to close. Then open the app to see if it works as expected.

2. Restart your device

Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.

3. Check for updates

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.

4. Delete the app, then redownload it

Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.

While we understand you're not having issues with the app quitting or not responding, the steps above can help with troubleshooting other unexpected issues as well.
