I have the latest non-paid/non-unlocked version of the Plex iOS app. I'm having trouble streaming from my iOS app (connected to my Synology NAS) to my Chromecast. Chromecast otherwise works on other apps. I can stream the video directly to my phone with no issues. It is only when I try to stream to the Chromecast that I have issues. The issue is that there is a spinner and it just keeps spinning and nothing shows up on my Chromecast to show that it is connected.
Any ideas as to what's going on / how to fix?
