Hi, I have heard so many good things about Plex but... what exactly does it do? I currently have Sky Q, Apple TV, Amazon prime and I think will get Netflix soon. I have also got Apple Music plus loads of photos etc from all phones etc. I have had an email offering discount on lifetime membership to Plex and it says about being able to record and stream the Sky Q amongst other thing but how does it all connect up? Sorry for sounding dumb!
