Love plex
To get full features you have to subscribe to the plex service. I rarely spend money on apps because there are usually free ones that do good enough. However, after a couple months of using plex I went ahead and paid for a lifetime subscription. They have done a great job with the plex family of apps. iPhone sync is still slow for me but I can live with it. I just sync to google drive and view from there. Keep up the good work guys.
