That would mean 3% to 11% year-over-year growth.Facebook said it’s being hit by a combination of factors, including privacy changes to Apple’s iOS and macroeconomic challenges. It blamed the lower-than-expected growth in part on inflation and supply chain issues that are impacting advertisers’ budgets.There’s also a shift to products that don’t generate as much revenue as its core news feed. For example, people are spending more time on its Reels videos.“On the impressions side, we expect continued headwinds from both increased competition for people’s time and a shift of engagement within our apps towards video surfaces like Reels, which monetize at lower rates than Feed and Stories,” Facebook said.cnbc.com
