Hi there! I see your Flashscore app on your iPhone running iOS 15.8.5 isn't working. Could you tell me a bit more about what's happening? For example, does the app fail to open, freeze, crash, or is some specific feature not working?

In the meantime, here are some simple steps to start troubleshooting:

1. Close and Restart the App: Double-click the home button (or swipe up from the bottom and pause, depending on your iPhone model) to see your recently used apps, then swipe the Flashscore app up to close it fully. After that, open the app again to see if that resolves the issue.

2. Check for App Updates: Go to the App Store, tap your profile icon, and scroll down to see if there's an update available for Flashscore. Installing the latest version can fix bugs.

3. Restart Your iPhone: Hold down the power button and slide to power off, then turn your iPhone back on. This refreshes the device's system and can clear temporary glitches.

If these don't work, you might consider uninstalling and reinstalling the Flashscore app on your iPhone. This refreshes the app and clears potential corrupted data.

Let me know if you’ve tried any of these already or if there are any specific error messages or behaviors you see. We can dig deeper if needed!
