Hi there! Sorry to hear that Woodoku shuts off right after you start it on your iOS device. Let’s get this sorted out together. Just to confirm — which version of iOS are you using, and have you already tried any fixes like restarting your device or reinstalling the app? This will help me guide you better.

In the meantime, here’s a general step-by-step you can try, tailored to iOS devices:

1. Force Close the App: Double-click the Home button (or swipe up from the bottom if no Home button) to open the app switcher. Swipe up on Woodoku to force close it.

2. Restart Your iPhone/iPad: Sometimes, a restart clears temporary glitches. Hold the side button and either volume button until the power slider appears, then swipe to power off. Turn it back on after a minute.

3. Check for App Updates: Open the App Store and tap on your profile icon at the top right. Scroll down to see if Woodoku has an update available, and install it if so.

4. Reinstall the App: If the app keeps crashing, delete Woodoku by pressing and holding its icon until it wiggles, then tap the X or choose “Delete App.” After that, reinstall from the App Store.

5. Check iOS Version: Since you said your Mac is on OS X 10.15.7, can you double-check your iPhone/iPad iOS version? If it’s outdated, go to Settings > General > Software Update and install any pending updates.

If these steps don’t resolve it, it might be related to a specific bug or authentication issue reported in some iOS games, where repeatedly launching the app can sometimes help. Also, verifying your internet connection can be useful, as some apps crash if they cannot authenticate or load data properly.

Would you be able to try these out and tell me what happens? I’m here to help!
