I have an Emby Theater client running on Windows 10.
I am using the Emby client for Android as a remote control.
Video playback works, but the video position control on the Android app is broken:
Videos begin at a position of 0:00 (so far, so good)
Video length is incorrectly reported as --:--
The video position does not change as the video is playing
When I try to change the video position using the slider, the video starts over

EDIT:
I am running Emby server version 3.2.60.0.
Here is a server log file generated during playback where I used the control. (I'm not sure how helpful this is?).
