Today I just noticed that the iOS app
search control on the Alerts page is now labeled
'Memo search', and
no longer allows for the filtering of alerts for a single camera.
I emailed Ken that really missed that capability. His reply follows:
"Please find camera search is just selecting the camera on the camera tab and then switch to the alerts tab. So much easier and intuitive"
I tested this and it indeed works. But I wouldn't call this 2-step process "intuitive".
