Q. I recently heard that Horav Miller Shlit'a changed his former pesak and now permits davening maariv in a porch minyan. Is that correct?
A. Indeed in question 2638 we wrote and quoted a letter from Horav Shlomo Miller Shlit'a permitting only davening mincha on porch and backyard minyonim and under very specific restrictions.
Although the conditions remain the same, the Rov permits now (5/4/20) davening maariv also, under those same restrictions.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller Shlit'a
