Hi! I see that your Substack app crashes specifically when you try to use the search tool on your iPhone. To get started, can you tell me a bit more? For example:
- Are you using the latest version of the Substack app installed from the App Store?
- Have you tried restarting your iPhone or reinstalling the app?
- Is your internet connection stable when this happens?

In the meantime, here are some troubleshooting steps tailored for your iPhone running iOS 18.6.2:

1. Restart the Substack app:
Swipe up from the bottom of the screen (or double-click the Home button if your iPhone has one) to open the app switcher. Swipe the Substack app off the screen to close it completely. Then open it again and try the search tool.

2. Restart your iPhone:
Sometimes a quick restart clears temporary glitches. Hold the side button and volume button, slide to power off, wait 30 seconds, and power it back on.

3. Update the Substack app:
Open the App Store, tap your profile icon at the top right, scroll down to see if Substack has an update available, and update if so.

4. Reinstall the app:
If the above don’t help, delete the Substack app by pressing and holding its icon until it wiggles, then tap the "X" or "Remove App." After that, reinstall it fresh from the App Store.

5. Clear cache and settings (if available):
Substack apps might have an option in settings to clear cache or reset app data. Check for this and try it.

6. Check network and VPN:
Make sure you are on a stable Wi-Fi or cellular network. Disable any VPN or proxy temporarily to see if that helps.

If it still crashes after trying these steps, it could be a bug related to the search tool feature in the current app version. In that case, reporting the issue with details to Substack support at [email protected] might be needed.

One user thread on Reddit mentioned similar crashing issues and suggested reinstalling the app helped in some cases1.

Let me know how these steps go, and if it still crashes, we can explore more specific fixes! Are you satisfied with this guidance so far?
