Cons
Con Extremely buggy
Around mid-2015 Downcast implemented some code that started to leave infinite loop processes that have the potential to cause the phone to heat up, lag, crash Downcast, or crash other apps. The bugs have only continued to get worse. Go with Overcast or Pocket Casts, or even Podcatcher for the Downcast feel.
Con Doesn't sync with iTunes
Con Needs registration
You need a PLEX account even if you use it on your local LAN.
Con Proprietary software
Unfree software.
Con No gapless audio-playback
Plex still does not support gapless playback of audio files such as mp3 or FLAC.
Con Playback error: This server is not powerful enough to convert video
More hardware requirements on Plex due to a useless/non-intuitive transcoder. When using lower spec hardware (eg SBC) Plex will not transcode or play HD+ videos. When compared to other packages (eg Jellyfin which transcodes nicely using FFMeg), Plex falls short on video playback and transcode settings to get videos to play (fastest/lightest option still fails).
