Google admitted that one of its apps violated the same policies as a Facebook app that landed the social network in hot water with Apple.
Apple revoked Facebook's enterprise certificates after a TechCrunch report revealed that the company had been secretly distributing a "Facebook Research" app to members of a program that allowed the firm to collect data on how they used their devices.
