Hey @hadarhubara10. I checked your account to confirm that there is still one existing cron job in one of your projects. That does need to be removed before you can add two new cron jobs as the Hobby scheduling limit is 2 cron jobs triggered once per day.
To delete the existing cron job, you need to remove it from the vercel.json config and create a new production deployment (e.g. push the change to your main branch or use vercel deploy --prod). Please give that a try and let me know whether or not it works for you.
