I don’t know about that specific issue but if you search the web for: paramount+ super bowl
You do see a lot of reports of crashing and messages like: "Sorry, this video is currently unavailable." It’s amusing that someone was running a commercial during the Super Bowl about breaking the internet and apparently it was breaking at the time. (Well just Paramount+ was breaking, but that phrase is usually used somewhat loosely!😀)
Based on your time of posting, I’m wondering if you were watching late and the link expired?
Paramount+ had major problems delivering the Superbowl, as did Fubo and YouTube+. Your timing may be coincidental.
