"We have had our Enterprise Certification, which enables our internal employee applications, restored. We are in the process of getting our internal apps up and running," a Facebook spokesman told CNBC in a statement. "To be clear, this didn't have an impact on our consumer-facing services."
Apple had revoked Facebook's certificate on Tuesday after TechCrunch reported that the social media company had used the certificate for an app that collected data on the smartphone usage of opted-in users. Apple said that use was in breech of the companies' agreements. Later, Apple revoked Google's enterprise certificate for similar reasons.
The certificate revocation prevented internal Facebook apps from working. Those included apps used by employees to test new features as well as use internal company services.
