If your Total Connect 2.0 app is crashing, here are the recommended troubleshooting steps you should follow:

1. Update the App
- Ensure you are running the latest version of the Total Connect 2.0 app. Honeywell has previously released updates that specifically fixed crashing issues, so updating may resolve the problem immediately1.

2. Avoid Editing Navigation Order (iOS Specific)
- Some instances of persistent crashes, especially on iPhones, have been linked to changing the "navigation order" in the app's settings. If you recently changed these settings, try uninstalling and reinstalling the app without modifying the navigation order afterwards. This has proven to solve the issue in certain cases2.

3. Operating System Updates
- Make sure your device's operating system is up to date. Honeywell has recommended upgrading to the newest version of your mobile OS as outdated operating systems may contribute to app instability2.

4. Reinstall the App
- Delete the Total Connect 2.0 app from your device and reinstall it from the official app store. Perform a fresh download and log in again without altering advanced settings unless necessary2.

5. Device Backup and Restore (iOS)
- For iPhone users, if updating the OS and app don’t help, trying a full backup and restore of your device might resolve persistent issues2.

6. Check for System/Connection Errors
- If you are receiving error messages (such as "Something went wrong. Please try again." or connectivity issues), repeated attempts may resolve it. If not, these could indicate server-side or configuration issues warranting support contact4.

7. Seek Official Support
- If problems persist after these steps, contact Resideo or your security provider’s customer support for further diagnostics or to report new issues47.
