Hi! I understand you're getting a "check internet connection" message in the Turbo AI app and your notes are not syncing or loading. Let me help you get this sorted out.

To start troubleshooting:

1. Could you confirm if other internet-dependent apps or websites on your Windows device are working fine? This helps verify if your internet is stable overall.

2. The Turbo AI app can sometimes have temporary glitches. Please try these initial steps:
- Close and fully quit the Turbo AI app or browser tab.
- Relaunch the app or refresh the browser tab to force a sync refresh.

3. Make sure you are properly logged into your Turbo AI account on this device, as that is required for syncing your notes.

4. Since you're on Windows and using WebKit-based browsing, clearing your browser cache could help. This removes stored data that might interfere with loading your notes.

If you have already done any of the above or still have trouble, let me know which steps you tried and what happened. Then we can proceed deeper with settings or account checks.

Does this make sense so far? Would you like me to guide you through each step?
