Sync question.

I have plex pass mainly to sync/download movies to my phone to watch at work where there is no wifi and a very weak LTE signal. I sync/download at home on wifi network where plex server is located and all is fine. I watch movies at work and it works great. If I dont finish the movie, when I get home and phone gets on the wifi it resets the movie to where it was on the server not on the phone and now I have to fast forward, and try and figure out where in the movie I was to continue watching on either phone or server connected tv. Is there a setting can do something about this?

:frowning: No help from anyone?
