Which part stopped working?
Start with the visible symptom. It is more useful than treating every problem as an outage.
- The page will not open
- Refresh once. Try the homepage instead of an old title bookmark, then check whether other sites load normally.
- Search returns nothing
- Shorten the title, remove extra viewing words and reset filters. Add a year only when you need to distinguish versions.
- My List looks empty
- Check that you are in the same browser profile and not a private window. Use a saved backup if site data was cleared.
- The video buffers
- Work on the page actually playing it. Test a lower player quality and check the service's status or help information.
Fullscreen trouble
Use the selected player's fullscreen control. If the picture does not expand, leave fullscreen and try once more with the player focused. A catalog page opening correctly does not test another site's fullscreen behaviour. Check the service's browser support if the control remains unavailable.
Protect the useful part of your setup
Do not clear all browser storage as your first experiment. That can remove a local watchlist without fixing the underlying video problem. Make a backup before storage changes, and keep the exact title and error message when seeking help.
