Facebook couldn't agree with Apple and reduced the functionality of the game app

For six months Facebook has been trying to agree with Apple that its game service does not violate the rules of the App Store. However, all the attempts were unsuccessful - in the company's app store owners of iOS devices will only be able to download a reduced version of Facebook Gaming.
For the most part, the application is used by users to watch gaming video broadcasts, and only about 5% of the activity falls on games. However, it is the games that have become the stumbling block for companies. Apple is a fierce fighter against cloud gaming and requires a thorough check of every gaming application, so Instant Games gaming applications will not be available to the company's mobile device owners.
According to Facebook, the company's gaming community already exceeds 380 million gamers.
