TikTok video downloads but won't save to your device
TL;DR fix
On iPhone, Safari saves web downloads to Files, not Photos. Open Files > On My iPhone > Downloads, tap the video, hit the share icon, then Save Video. It'll now appear in your Camera Roll.
The file downloaded successfully but you can't find it? That's usually a permission issue on your device, not a problem with the file itself. Here's where each platform hides downloaded videos and how to force them to appear.
