Zoom has removed the Facebook SDK in its iOS client and has reconfigured the feature so that users will still be able to log in with Facebook via their browser. Zoom is reviewing its process and protocols for implementing these features in the future to ensure this does not happen again. We sincerely apologize for the concern this has caused, and remain firmly committed to the protection of our users privacy. We would like to thank Joseph Cox from Motherboard for bringing this to our attention here. We will update the latest version of our application thats already available at 2:30 p.m. Pacific time on March 27, 2020, in order for these changes to take hold.”]
