Check for iOS updates

There may be system updates. These updates may fix this. To check and install iOS updates, go to Settings > General > Software Update.

The problematic app may have updates. Keeping your apps up to date is a good idea. Because these updates often fix bugs that may be causing your problem. Updating your app may help you.

1. Open the App Store.
2. Tap your account avatar in the upper-right corner of the screen
3. In the ”Available Updates” section, find the app update you want to install and then tap ”Update.”

The next thing to do if an app is still not working after iOS 17 update is to force close it. Apps can crash or stop working unexpectedly if it’s unable to run a required task at a time.

To delete your app, tap and hold the app until it jiggles and then tap the delete (X) icon to remove the app. Then press the home button or swipe up from the bottom of the screen to stop the jiggling. Now go to the App Store then search for the app you just removed and then tap the Redownload icon to reinstall this app.
