Can’t create cache folder from external drive

Hi

I am using popcorn on Gbox tv box, the available drive space is not enough to download movies, I mounted an external drive but popcorn is not recognising it, can anyone help me plz?

Some times it is a permission issue by the system. I don’t know how that works in your case but on Linux I need to get admin access to PT, and I often get this kind of issue on some drives that I cannot edit or access.
