Hi there! I understand that you and your partner have been using the MoodMe app for some time, but now suddenly you're both unable to submit a mood, and no data or information is showing up. Let's work through this together.

First, just to clarify a couple of things:
- Are you both experiencing this issue on your iPhones running iOS 18.7?
- Is the app crashing, freezing, or just not saving the mood submissions?
- Have you tried restarting the app or your phones recently?

Assuming the app is just not submitting moods, here’s a step-by-step approach we can try:

1. Check Internet Connection: Make sure both phones have a stable internet connection (Wi-Fi or mobile data). Sometimes mood data can't submit without connectivity.

2. Restart the App:
- Double tap the Home button or swipe up the app preview (depending on your iPhone model) and swipe the MoodMe app off the screen to close it.
- Then reopen the app and try submitting a mood again.

3. Update the App:
- Go to the App Store, tap your profile icon, and check if there’s an update available for MoodMe. An outdated app version might cause syncing issues.

4. Log Out and Log Back In:
- Sometimes user sessions can get stuck. Logging out of your account then logging back in can refresh your session and data sync.

5. Check App Permissions:
- On your iPhone, go to Settings > MoodMe app and ensure all necessary permissions are enabled (like cellular data access).

6. Free Up Storage:
- Make sure you have enough storage available as lack of space can sometimes prevent data saving.

7. Reinstall the App:
- If none of the above works, try uninstalling and reinstalling MoodMe. Just be careful to back up any important data if possible.

If you’ve already tried these steps or if the issue persists after attempting them, next we might want to check if there’s any account or server-side problem causing the disruption. In that case, I would recommend contacting MoodMe support at [email protected] for assistance, as they can look deeper into your account data and server status.

Would you like me to guide you through any of these steps in more detail? And did you notice any error messages or other symptoms when you try to submit a mood?

Are you satisfied with the solution I provided so far?
