Google has confirmed a bizarre new bug affecting all Gmail users, where the service issues a sender warning for every email received. The bug first struck on Thursday, with Gmail attaching a security notice reserved for suspect emails to everything that arrives in a recipient’s inbox. Normally, Gmail only attaches this message to emails where the service has doubts about the sender, hence flagging it as a potential security risk that you may wish to move to spam. Why has the technology really failed during Covid-19 when the world need it the most?
