If the address will not open
Switch the phone between Wi-Fi and mobile data first: school, office and public networks often filter streaming names. Then check the address against the addresses page, since the tv and vercel addresses are separate sites.
If a page looks broken
Reload it, then clear this site's data in your browser settings. A saved older copy is the usual cause, and a fresh load brings the rounded cards and hero back.
If a video will not start
Videos play on the service you open from Watch now, so the fix is there: reload its player, sign in again, or pick the next service on the list. Check that your viewing country on BingeFlix matches where you are.
If your list is empty
My List lives in your browser. A private window, another browser or cleared site data starts fresh, and your list returns in the browser where you built it.
