I might be the only one experiencing this, but every time I look at a recipe, my conversion says e.g. 350F [350C] which is obviously not correct. I have used this extension for a while, now and love it, but this lack of accuracy is making me want to uninstall it as it is not doing what I need. Can anyone else say if this is happening to them ?
