The update comes just days after CNBC announced that Facebook security team had use location information to track missing practitioners and users who are considered dangerous.
Granting access to your site is an "all or nothing" deal: you must either not allow the app to view your location at all, or you must use it fully. That's why Android is working. Google requires applications to license your site without the choice of when to use them location data you.
Fortunately, Google can resolve this issue in the near future. The first leaks from the Android Q demonstrate that the next version of the operating system will allow users to grant access "only when using the application", just like in iOS.
In iOS, Apple already offers the option block an application from using your location in the background, therefore, no updating is required.
Of course, Facebook says it is going to send notifications anyway to users iOS and Android, asking them to review their location settings.
