I have taken control of everything (I think) for my U19 team for FC Porto. I cannot see where to edit coach assignments for my U19 or B team.
Can this not be done?
I used to do it in FM 2019.
sorry for the late reply, I saw your question because I was looking for the same answer, however I managed to find out where to edit coach assignments for B and U19 team.
You have to go to Dev. Centre (left menu), then you have to click on Staff on the top menu and choose B or U19. On the page relative to the staff you have to click on "Coaching team" and then on page bottom you have to click on "Training Assignments" and then on top you have to click on "Edit coach assignments".
It was much simpler in FM19 - they have made it a lot harder to find this screen in FM20.
