Hi there! I'm sorry to hear that your Kohl's app is freezing on your iPhone. That can definitely be frustrating. Let's see if we can resolve this together.

1. Restart the App: Sometimes, simply closing and reopening the app can help. Double-tap the home button (or swipe up from the bottom if you don't have a home button) to see your open apps, and swipe the Kohl's app away to close it. Then, reopen it.

2. Check for App Updates: Ensure that you have the latest version of the Kohl's app. Open the App Store, go to Updates, and see if there's an update available for the Kohl's app.

3. Internet Connection: Make sure your internet connection is stable. You can try toggling Airplane mode on and off to reset your connection or disconnecting and reconnecting to your Wi-Fi.

4. Clear App Cache (if applicable): Sometimes, the app can get bogged down with cached data. On iOS, you usually can't clear the cache directly, but you can uninstall and reinstall the app, which will effectively clear that data. To do this, press and hold the Kohl's app icon until the options appear, select "Remove App," and then download it again from the App Store.

5. Software Update: Ensure that your iPhone is running the latest version of iOS. You can check this by going to Settings > General > Software Update.

If you've tried these steps and the issue continues to occur, it might be worth checking with higher-level support or seeing if there are any known outages affecting the Kohl's app.

Are you satisfied with the solution I provided, or is there anything else you’d like assistance with?
