Luis It started working a couple hours ago, so was temporary. Probably caused by the new ability to add custom bangs natively on assistant settings 🎉
Now the only thing missing is, you can't add a custom bang to the code bot, because it has no configure option. So I'm left with my https://kagi.com/assistant?q=%s&profile=code
even though I was able to delete the other Custom Bangs and just configure it on my assistants.
