Hi there! I understand that when you text in the Dopple.AI app, it just starts "thinking" and never responds. Let's work together to get that sorted out.

To begin with, could you tell me a bit more? For example:
- Are you using Dopple.AI on a browser or the app on your Windows device?
- Is your internet connection stable when this happens?
- Have you tried closing and reopening the app or refreshing the page?
- Did this problem start recently or has it been ongoing?

Meanwhile, here's a simple step-by-step to try that often resolves this issue:

1. Clear your browser cache and cookies: Sometimes old data causes the AI to hang while loading responses. Since you are on Windows with a browser using WebKit, clearing cache should help.
- In your browser settings, find Privacy or History settings.
- Choose to clear cache and cookies.
- Restart the browser and log back into Dopple.AI.

2. Check your internet connection: Confirm your connection is stable with a quick speed test or try opening other websites.

3. Try simpler inputs: Some reports suggest using shorter or simpler messages helps if the AI seems stuck processing complex requests.

4. Restart your device: Sometimes a full restart clears temporary glitches.

If after these steps the app still only "thinks" and does not reply, there might be a backend glitch or server issue for Dopple.AI at the moment.

If you'd like, I can look further into recent reports or known issues about Dopple.AI’s responsiveness for you.

Does this sound like a good place to start? Also, let me know what troubleshooting you've already tried if any!
