Originally I was doing it all manually to learn how they work, but was hoping the automations could do it so I could spend more time with Corporations. Apparently it doesn't work well.
Health was at 120 when I turned auto on, just to maintain it. Dropped to 80 in all my countries with auto on, and education priorities were all screwed up. Maybe they just aren't developed enough?
The health one seems to work fine, all it does is buy hospitals if you have enough people for them. The problem seems to be in the Education Priorities auto function.
