Hi there! I understand you're having trouble with your eHarmony account where messages cannot be read. Could you please tell me a bit more? For example, are the messages not showing up at all, or do you receive an error when trying to open them? Also, is this happening in the eHarmony app on your iPhone (iOS 18.6), or on the website? Knowing this will help me guide you better.

Meanwhile, here are a few initial steps that often help with message issues in the eHarmony app:

1. Restart your iPhone: Sometimes a simple restart refreshes the app and clears temporary glitches.
2. Check for app updates: Go to the App Store and make sure your eHarmony app is updated to the latest version.
3. Log out and log back in: Signing out of your account and then signing back in can reset the connection to the server.
4. Verify your subscription status: eHarmony often restricts messaging features to subscribed members. To check, open the App Store, tap your profile picture top right, then Subscriptions, and verify your eHarmony subscription is active.

If none of those help, you may also try uninstalling the eHarmony app and reinstalling it fresh. That can fix corrupted app data that's blocking messages from loading1.

Could you please try these and let me know which have been attempted or the results? Then we can dig deeper if needed!
