Hi there! I understand you're having trouble entering or submitting text in your Talkie messages, and that other Talkie instances aren't working either. Let's try to address this step by step.

1. Check Your Internet Connection: Make sure your internet connection is stable. Sometimes issues can arise from connectivity problems. You can try opening another website to see if it loads properly.

2. Browser Check: Since you're using WebKit on Windows 10, try clearing your browser's cache. Here’s how:
- Open your browser settings.
- Look for "Privacy and Security" or similar.
- Find the option to clear browsing data (make sure "Cached images and files" is checked) and then clear it.

3. Try a Different Browser: If clearing the cache doesn't help, try using a different browser to see if that resolves the issue. Sometimes there might be compatibility issues specific to the browser you're currently using.

4. Disable Extensions: If you have any browser extensions enabled, they might interfere with Talkie. You can disable them temporarily to check if that solves the problem.

5. Check for Updates: Ensure that your browser is up to date. Updates often fix bugs that could be causing your issue.

6. Look for Messages or Error Notifications: After you attempt to submit your text, see if there are any error messages or notifications within the Talkie app that could give clues about the problem.

If these steps don’t resolve the issue, I can look up additional support resources for you. Would you like me to do that?

Are you satisfied with the solution I provided?
