Found that version 8.8.5 would not let me select the playback speed. It is stuck at 1x. Also I could not select a date for playback when I click on the date. These are 2 important features for me so I stopped using this version and went back to version 8.8.4.

I would like to participate in the trial for the Argus 2E too please. I currently have the C1 Pro, C2 Pro and E1 Zoom and would like to review a battery operated camera.

Wanted to update on everyone on what Reolink said. They sent me a link to their older version of the software. I installed it and it does work. I did not uninstall V7.2.2.33 so I tried that again and to my surprise that is now working again. I cannot explain why but obviously very happy.
I have posted the link below to the older software in case anyone wants it.

I am also having the exact same problem, not playback on windows client after DST. I did sent a note to Reolink outlining the problem. Wait to see what they come back with.
