I have been using the sync feature of the Android App for quite a while to listen to music through my phone. Since the last update to the Plex Android mobile app, I have seen a large increase in the Plex app's data usage. It would seem I'm using about the same amount of data to play sync'd content as I would if I streamed it, about 1.5 gigs of music so far.
The local device is selected as the location. I deleted they sync'd content and the space available increases, so the content was on the device. I re-sync'd the content, but I'm still seeing data use when playing it.
Has anyone else noticed this?
