The phrase refers to a specific iteration of the TikTok application designed for Apple’s iOS operating system that predates the current, most up-to-date release. An example of its usage is in situations where users seek to revert to a version they prefer due to interface changes or device compatibility limitations.
The significance stems from the potential for enhanced device performance on older iPhones and iPads, or because a user might prefer a previous feature set or interface. Historically, users have sought archived releases due to compatibility issues with newer iOS versions, disliked changes in the updated application, or to bypass certain restrictions implemented in later updates.
