Hi.
I got suddenly pretty the same problem.
I am runing libreelec kodi on PC. On the beginning works great. Now I can only see folders, but I can't open them. Only works if I am opening from mac(apple).
I want to open it from android phone and doesn't work. I think I didn't changed anything.
I went through all settings and for me everything looks ok.
I have v.11.0.3
