Found after this upgrade the Playback screen in the webgui won't show me the timeline at the bottom anymore (chrome), hence can't see when events happened. Strangely I can view videos/events in gdmss app though.
After going from
to this version
(Yes I know a big jump)
The playback tab no longer shows video or the timescale bar at the bottom (the one with events, etc).
Live video works well in standard chrome however.
I'm recording to SDCard not NAS/NVR.
