Hi! Thanks for reaching out about the issue with sending messages on Talkie. I’d like to get a bit more detail so I can help you best:

- Are you able to type the messages but they just don’t go through when you hit send?
- Are you seeing any error messages or notifications when the message fails?
- Is this happening every time or only sometimes?
- Are you using the Talkie app or accessing it through a browser on your Mac?
- Have you tried restarting the app or your Mac already?

These details will help me narrow down the cause. Meanwhile, a few common simple steps that often solve sending issues on Talkie include:

1. Check your internet connection to ensure it’s stable. Since you're on macOS 10.15.7, try switching between Wi-Fi networks or plug in via Ethernet if available.
2. Sign out and sign back in to your Talkie account. Sometimes session-related hiccups prevent sending.
3. Clear browser cache if you’re using Talkie in a web browser (Safari, Chrome, etc.). You can do this in Safari by going to Safari > Preferences > Privacy > Manage Website Data, then remove Talkie-related data.
4. Update the app if you're using the Talkie app on macOS or check for system updates on your Mac to ensure compatibility.

If you’ve already done some of these, please let me know which ones so we can try more advanced steps like checking for account message limits or any server-side problems reported1.

Let's start there—how does the app behave exactly when you try to send?
