Hi there! I see you're having trouble with your newly created story in sekai, where you get a "Message failed to send" error. I can definitely help with that. Could you tell me a bit more about when exactly this error pops up? For example, is it when you try to post, send, or share the story? Also, are you connected to a stable internet connection when this happens?

Meanwhile, let's try some basic checks to start:

1. Check your internet connection: Make sure you have a strong and stable Wi-Fi or mobile data connection.
2. Restart the app or browser: Sometimes, simply closing and reopening sekai can resolve temporary glitches.
3. Clear cache and cookies: Since you're on WebKit with Android 10, clearing the browser cache and cookies might help if there's stale data causing the issue.
4. Check story content: If there is anything in the story like special characters or unsupported media, sometimes the app refuses to send it.
5. Try a different network: Sometimes, restrictions on a network can interrupt sending data.

If you've tried these already or the problem persists, let me know, and we can dig into advanced troubleshooting! Also, do you see any additional error codes or messages along with "Message failed to send"?
