Hi there! I understand that the messages aren’t displaying in Messenger Kids and one contact won’t even open. I’m here to help you get this sorted out. Just so I get a clearer picture, is this happening with all messages or only with specific contacts except that one? Also, have you noticed if this problem started after an app update or something changed on the device?

Meanwhile, here are some steps we can try together on your iPhone running iOS 18.5:

1. Close and Reopen the App: Sometimes restarting the app can refresh message loading. Double-press the Home button or swipe up from the bottom if you use gestures, then swipe the Messenger Kids app off the screen to close it. Reopen it after a few seconds.

2. Restart Your Device: This can resolve temporary glitches. Press and hold the side button and either volume button, then slide to power off. Turn it back on after about 30 seconds.

3. Check Internet Connection: Make sure the iPhone has a stable internet connection, either Wi-Fi or cellular.

4. Update Messenger Kids: Open the App Store, tap your profile icon, then scroll down to see if an update for Messenger Kids is available. Installing the latest version often fixes bugs.

5. Check Storage Space: If your device is low on storage, it may cause problems in apps. Go to Settings > General > iPhone Storage to see if there’s enough free space.

6. Re-login to the App: Log out of Messenger Kids and log back in. This action refreshes your account data and connections.

If the issue remains, particularly with one contact that won’t open, there might be a data glitch specific to that chat. Sometimes clearing the app cache, or reinstalling the app can help:

7. Reinstall Messenger Kids: Press and hold the app icon until it jiggles, tap the ‘x’ to delete it, then reinstall it from the App Store. You will have to sign back in afterwards.

Also, please check if the problem occurs on another device logged into the same Messenger Kids account (if available), or ask the child’s parent account to check if they see any restrictions or blocks on that contact.

If none of these steps fix the issue, there could be a deeper account or server issue that needs further attention. In that case, I can assist with escalating to specialized Messenger Kids support for you.

Please let me know which steps you’ve tried and what you observe after doing each one, and we’ll continue from there! Does this plan sound good to you?
