问题 I would like to know, does deleting account from Firebase automatically logs user out? I mean, if I want to show him after deleting the login screen, then I just have to present that VC? I am asking this because if I do like this, it crashes and I think it is because the user doesn't exists anymore at this points. Am I right?
