Google’s email service was recently struck with a nasty bug that resulted in inadvertent deletion of some emails and other related issues. The issue reportedly happened days before the downtime that struck the service a few days back.
The bug led to deletion of emails, spam in the form of email being sent to a different email address, mislabeling of important messages as Trash or Spam. Google started notifying the users about this glitch that is said to have occurred between January 15 to 22.
The affected users were notified with the following message, as published by The Verge–
You may have been impacted by a recent issue in Gmail that inadvertently caused some actions (e.g. delete, report spam) taken while viewing a message to be applied to a different message. The issue occurred between January 15 and January 22 and is now fixed.
