Browsers require explicit permission before writing files to a folder. If folder access is unavailable, DPA Web downloads the CSV and JSON files normally.
For tagging, use these Layout, Zoom, and Pan controls. Do not rely on the external player's own fullscreen button — it hides the DPA strip below and gives no timing information either way.
Move the external video to the same match time in the provider page above. DPA cannot read or seek the external video — this step is manual. When the provider video is aligned, press Confirm Aligned to unlock tagging.
If the provider asks you to log in, log in normally — DPA never automates login.
