Hi! I see that every message you try to view in Messenger Kids shows “Message cannot be displayed.” Let’s get to the bottom of this together.

First, to help me understand better:
- Is this happening with messages from all contacts or just specific ones?
- Has this issue started recently or been ongoing for a while?
- Have you tried any steps so far to fix it?

Meanwhile, one straightforward trick that has helped others is this:
1. Open the Messenger Kids app on the child’s account.
2. Tap the child’s profile picture at the top left.
3. Select “Switch profiles.”
4. Instead of switching to another profile, simply tap the child’s profile picture again to return.

This action can sometimes “refresh” the message display and make the messages visible again1.

If that doesn’t work, we can also:
- Restart the device (your Mac running OS X 10.15.7).
- Make sure the app is updated to the latest version on the device.
- Check that there's enough storage space on the Mac as low storage can affect app performance.
- Confirm the internet connection is stable.
- If the app is web-based on the Mac, try clearing the browser cache or try a different browser.

Let me know how these go, and if the messages still won’t show, I can guide you through some advanced troubleshooting steps. Does this make sense so far?
