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

Quiet. No reports in the last two weeks, down from 2 a week at the late-September peak. A workaround is known.

Chat requests hang and time out after sending a message. Chat on Windows takes a very long time then fails with a Request ID or stays stuck; reported on 3.19 and 3.21.
