It can take up to 24 hours for ganache to set up and be useable after you make it. If you just made it today by tomorrow it should be fine. I’ve made white chocolate ganache but not with double cream, with 35% cream. I would give it more time to set up if you have just made it today. If you are unhappy with it tomorrow add more chocolate. I think it will be fine.
