No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

Growing. 1 report in the last 7 days and none the week before, down from 2 a week at the late-October peak. Not fixed, but the vendor replied on another bug in this theme, Oct 22.

Hook sessionTitle not applied in Remote Control app sessions. The title is applied locally and written to the transcript as a custom-title entry, but the app keeps its auto-generated title; /rename does update it.
