Basically the new iOS Beta was installed on a persons iPhone and one feature that's new, is it notifies you pretty loudly and visibly when an app is accessing parts of memory/the clipboard/some piece of hardware it's not supposed to. The alert was coming up when tiktok was in the background and the foreground, and the alert was "letter copies to clipboard", while someone typed a message in tiktok, or I believe any other app, and tiktok was accessing those characters. https://youtu.be/FAFEj888Gbw -edit- I was half right, tiktok accesses the clipboard and is "pasting" whatever's in the clipboard and sending to them.
