How to fix CardStar app crashes or not working?

  1. First, shut down the CardStar iPhone app and open it again.

    Any hiccups are usually cleared out of the app's cache when you restart it. To force close and relaunch the CardStar app on your iPhone, follow these steps:

    1. You can access the app switcher by making a vertical glide from the bottom of the screen to the center.
    2. Find the CardStar app.
    3. To exit the app, swipe it up. It's the same procedure to terminate any remaining background applications.
    4. The most current updates won't take effect until you restart your iPhone, so be sure to do that.

  2. Install the most recent version of the CardStar iOS app:
    1. Launch the CardStar App Store on your iPhone's display.
    2. Look for the CardStar app. To open it, just click the button when you find it.
    3. An "Update" button will appear if there is a new version available to download.

  3. Removing and reinstalling an CardStar iPhone app:

    Any damaged temporary files or data that may have been the cause of the app crashing or failing to load will be removed when you uninstall the CardStar app from your iPhone. After you have deleted an app, you can reinstall it via the App Store on your iPhone or iPad.

  4. Update your iPhone to the latest iOS version available:

    If the issue is related to a bug in the previous iOS version, updating to the most recent version should fix it. Here's how: go to your device's Settings » General » Software Update.

  5. Other options

    If you're having trouble, please contact customer care by phone or through the website's contact page. Contact CardStar customer support or visit the CardStar contact page to report the issue and get assistance.

How to fix CardStar payment issue while purchasing app or upgrades?

Here's how to resolve any payment issues you may be having: Carefully double-check your payment information (credit card or debit card) and its expiration date. Make sure your bank account has adequate funds in it. Possible reasons why you can't upgrade include not having enough money in your account or problems with the CardStar site's payment mechanism. That's a dealbreaker, obviously, but don’t fret just yet. Wait a little while and then try again.
