Instant messaging service WhatsApp went down for thousands of users around the world early Tuesday morning before the issue was “fixed.” Concerned users vented their frustration about the service blackout on the Meta-owned platform, with many saying they were able to access their conversations but could not send or receive new messages. A Whatsapp spokesperson said the company had detected an undisclosed issue with the platform that was quickly remedied. “We know people had trouble sending messages on WhatsApp today,” the spokesperson said in a statement to Bloomberg. “We’ve fixed the issue and apologize for any inconvenience.”
