Just called support and the agent stated that it’s not with this recent update but in the next update (4.5.5) it will be back. There just isn’t a time frame on when yet.
I am also very disappointed with the playback feature removed. I have over 10 cameras and pay annual subscription to store in cloud and that yellow marker feature was very useful to decide what timeline to look at. I will move to Nest if this feature is not brought back soon.
Just spoke with a representative & he stated that some people have it but most are still experiencing this issue. They are currently working on it and plan to have an app update later this week.
PS; He did have me uninstall and reinstall the app cause that worked for some. It did not for me but something to try
