'Signal, an encrypted messaging app that competes with other services including Facebook's WhatsApp, said Thursday that verification codes used to create new accounts were delayed because of a flood of new users. From a report:

"We are working with carriers to resolve this as quickly as possible," the non-profit foundation said in a tweet. "Hang in there." The surge came just hours after Elon Musk endorsed the service and amid reported changes to WhatsApp's terms of service.'
