This move by Apple reportedly caused on Wednesday.
That discovery of Facebook's methodology to all of this led Apple to pull the certificate for Facebook's internal apps based on the same certificate.
Mashable reports that Facebook shows no remorse for their latest scandal in which they were caught possibly spying on teenagers via an app for the goal of "market research". The tech blog TechCrunch reported on Tuesday that Facebook paid people about $20 a month to install and use the Facebook Research app.
But the company seemed confident it would quickly regain its access.
On Monday it was revealed that Facebook had used its enterprise access to distribute a market research app to the public, including teenagers. Apps that it said "may not work" included internal versions of Facebook, Workplace, Instagram and the Ride app, which helps workers with transportation.
Apple's sudden shutdown of Facebook's internal apps for iOS created enough chaos this week that some working for the social network company were openly talking about quitting, according to reports.
On one level, Apple's actions against Facebook and Google are simply the enforcement of its developer policies. A Google spokesperson told ZDNet afterwards: "We're working with Apple to fix a temporary disruption to some of our corporate iOS apps, which we expect will be resolved soon".
Apple blocking Google's apps is likely to do with its Screenwise Meter app, which tracks how people use their smartphones.
"The Screenwise Meter iOS app should not have operated under Apple's developer enterprise program - this was a mistake, and we apologize".
"We have had our Enterprise Certification, which enables our internal employee applications, restored", Facebook said in a statement. Without those certificates, they could no longer do their jobs testing new features or use internal services dependent on Apple. If popular apps, such as Facebook's Instagram and Google Maps, aren't kept up to date on iPhones, consumers might switch to handsets that run on Google's Android operating system. It's unclear how this will impact that deal when renewal discussions begin. That's a no-no, according to Apple's rules.
