Google is repairing a glitch that caused critiques to vanish from Google Business Profiles. Reviews are a restaurant’s main source of income, and taking them away can drastically decrease revenue. A resolution is in progress, and many reviews have been brought back, Google's Search Liaison stated on Twitter. Google is conscious of this bug and has been steadily dealing with it, and that labor will carry on, Danny Sullivan said in a response to Mike Blumenthal, who says he notified the bug a week ago. Customers' reviews are linked with a particular CID number, which means altering the CID eradicates the reviews, which should never occur, particularly not when using Google's recommended edits.
