Those numbers are down 9% and 2.6%, respectively, from the fourth quarter.Revenue climbed almost 43% from a year earlier.

That was below Refinitiv expectations of 23.9% growth.Advertisers’ willingness to spend on Pinterest’s services has fluctuated due to pandemic-related factors, including supply chain issues, rising commodity prices and labor shortages, the company said in a financial filing. The company also said that it’s experienced and may continue to see lower levels of user engagement, growth and retention rates as pandemic restrictions begin to lessen.Pinterest noted that Apple’s iOS privacy changes have affected its “ability to track user actions off our platform and connect their interactions with on-platform advertising.” While the company didn’t provide specific details about how Apple’s new feature affected its financial results, other social media apps like Snap and Facebook said the change was a significant drag on their business in the latest quarter.The company did not address reports about a potential takeover by PayPal.PayPal was reportedly in talks last month to buy Pinterest, though the payments company subsequently said it was not pursuing a deal.
