Thanks Phil. Likely a typo - but the release notes refer to build 190822, but the file on the portal is 190821, which is the same build that was there under 4.22.000 previously
Some feedback to Hikvision on this build - while the red marks now appear when using remote (web) playback the icons to enable this only appear when useing Internet Explorer. Using Firefox and Chrome on Windows shows the icon to change from single camera playback view to 4, 9 etc but the icon to show event marks is missing in those browsers.
Dragging the playback time bar works smoothly in Firebox but jumps about a lot when tryign this in IE. So IE shows red mark but hard to control the playback position. FF & Chrome smoother to move the playback time about but no event marks!
