I made my first post. But on decster.ai, when I try to complete the challenge and paste the link to the post , I always get the message: "This post is too old. Write a new one." But the post was only 3 hours old at the time, and now it’s been 19 hours, and it still doesn’t work. What can I do? Is it because I didn’t use the template, or because I posted it in “Help & Troubleshooting”?
