Hi there! I understand that on your Mac running OS X 10.15.7, when you use The Weather Channel app, the charts show up blank except for the monthly chart. Let's work through this together to get those charts displaying properly.

First, can you tell me if this happens consistently for all charts aside from the monthly one? Also, have you tried any fixes like restarting the app or the device already?

In the meantime, here’s a step-by-step approach we can try:

1. Restart the App: Quit The Weather Channel app fully and then reopen it. Sometimes the app needs a fresh start to reload all data correctly.

2. Check for App Updates: Make sure your Weather Channel app is updated to the latest version available for macOS. Outdated versions might have bugs causing display issues.

3. Clear App Cache or Data: Some apps store temporary data that can become corrupt. Although macOS apps don’t always offer a clear cache option, try signing out of the app (if you’re signed in) and then sign back in.

4. Reinstall the App: If the above doesn’t help, uninstall The Weather Channel app completely from your Mac and then reinstall it. This can clear any corruption causing charts to fail loading except the monthly one.

5. Check Network and DNS Settings: Since charts might rely on fetching dynamic data, ensure your internet connection is stable. Also, sometimes DNS settings or blockers can interfere with content loading—if you use any VPNs, ad blockers, or DNS filters, try disabling them temporarily to test.

If you've already tried some of these, please let me know which ones, and we can explore more advanced troubleshooting.

Are you comfortable trying these steps now? And did you notice any patterns, such as only certain charts being blank or the issue happening at certain times?

Looking forward to your reply!
