Hi! I’m Grace Wilson. I see your iOS Katasymbol app crashes after briefly connecting. Let’s get to the root of this together.

To help you best, could you tell me a bit more? For example:
- Does the app crash right after launching or only after connecting to something specific?
- What kind of connection is it—Wi-Fi, Bluetooth, or something else?
- Have you tried any steps so far like restarting your phone or reinstalling the app?

Meanwhile, here’s a step-by-step we can try to address common causes of app crashes on iOS 18.7:

1. Restart your iPhone: Sometimes a fresh start clears temporary glitches. Hold the power button, then slide to power off. Turn it back on.
2. Update Katasymbol app: Open the App Store, tap your profile icon, scroll to available updates, and update if Katasymbol is listed.
3. Reinstall the app: Press and hold the Katasymbol app icon, select “Remove App,” then delete. Re-download it fresh from the App Store.
4. Check Connection Type: If the crash happens on connection, try switching off Bluetooth or Wi-Fi briefly to see if the app runs without connecting.
5. Ensure iOS is up to date: You're on iOS 18.7, which is recent, but a quick look in Settings > General > Software Update can’t hurt.
6. Close other apps: Double-tap the Home or swipe up the app switcher, swipe away other apps that might conflict.
7. Check permissions: Go to Settings > Katasymbol and ensure it has permission to use Bluetooth or network features it might need.

If these basic steps don’t help, it might be a specific bug when connecting a certain device or network. That’s helpful info to pass along if you contact support.

Let me know if you notice when exactly it crashes or if you want help walking through these steps! Are you able to test one step right now?
