There might be a few things interfering with Copilot’s image generation. Here are a few tricks to try:
First, clearing your cookies can sometimes solve this, along with removing any extensions you have in Microsoft Edge and disconnecting from a VPN if you’re using one. If it’s still not working, try switching to inPrivate browsing to see if that helps.
You might also want to test it in a different browser, just in case it’s a browser-specific issue. And if you have another Microsoft account, try logging in with that to see if the issue is tied to your main account.
If everything else checks out, it’s possible the Bing image server is having a glitch. Keep in mind there’s also a daily limit of 25 image generations per account, so it could be that as well. Let me know if any of these help!
