The iPhone maker released the latest version of its mobile operating system, iOS 13, last week and the company followed this up with the recent release of iOS 13.1 and iPadOS 13.1. However, Apple has warned users of an issue affecting third-party keyboard apps in a brief advisory, which reads: “Third-party keyboard extensions in iOS can be designed to run entirely standalone, without access to external services, or they can request “full access” to provide additional features through network access. Apple has discovered a bug in iOS 13 and iPadOS that can result in keyboard extensions being granted full access even if you haven’t approved this access.”
