Some users are reporting that the sign-up option for Twitter Blue subscription has disappeared a day after going live.
Meanwhile, the Federal Trade Commission said it was watching events with "deep concern".
During his first few weeks as CEO, Mr Musk laid off some 3,700 workers - but had not spoken to the majority of staff who remained at Twitter.
His first email to employees warned: "The road ahead is arduous and will require intense work to succeed."
"Without significant subscription revenue, there is a good chance Twitter will not survive the upcoming economic downturn," he said.
