A useful support screenshot can reveal more than the problem
An agent records an upload issue. The opening frame looks suitable for training, but scrolling reveals an account identifier, a notification displays a customer name and the narration repeats it. Cropping the first frame would miss most of the exposure.
This hypothetical example shows why privacy review covers frames, audio, text, attachments and the destination. “Privacy-safe” describes a risk-reduction process, not a guarantee of anonymity, universal security or legal compliance.
