Hi there! I see you’re having trouble with the ECOVACS HOME app not working on your iPhone. Let’s work through this together and get it sorted out.

To start, could you tell me a bit more about what exactly is happening? For example:
- Does the app fail to open at all, or does it open but not connect to your robot?
- Are you seeing any error messages?
- Did this issue start happening after an update of the app or your iOS (version 18.6)?

Meanwhile, here are some straightforward steps that usually help with app issues on iOS:

1. Force Close the App & Restart Your iPhone
Double-click the Home button (or swipe up from the bottom if no Home button) to see open apps, then swipe the ECOVACS HOME app off the screen to close it. Then, restart your iPhone completely and open the app again.

2. Check App Permissions
Go to Settings > ECOVACS HOME and make sure it has permission to use Wi-Fi, Location Services, and Mobile Data. The app needs these for connecting to your robot.

3. Reinstall the ECOVACS HOME App
Delete the app from your iPhone, then download the latest version again from the App Store. This clears any corrupted cache or outdated files that might be causing trouble.

4. Check Your Wi-Fi Network
Make sure your iPhone is connected to a 2.4 GHz Wi-Fi network (not 5 GHz), as many ECOVACS robots only connect on 2.4 GHz. Also confirm your network is stable.

If you’ve already tried any of these steps, just let me know which ones, and we can move on to more specific troubleshooting. Otherwise, please try these and tell me what happens!

Are you satisfied with these initial suggestions, or shall we dig deeper?
