    Unity Learn videos within various tutorials cannot be played. I'm seeing console errors in my browser devtools that seem potentially related (see attached screenshots).

    Here are two unrelated tutorials that I am seeing this issue on, which leads me to believe this affecting the entire Learn site (though I'm happy to be proven wrong here)

    - Junior Programmer Pathway Lesson 1.1 (fails with DOMException for handleSource on MediaSource) https://learn.unity.com/tutorial/se...0200e9de0&projectId=5caccdfbedbc2a3cef0efe63#

    - Unity + USC: Design and Publish Your Original Game (fails with DOMException for handleSource on MediaSource AND displays a 429 server error) https://learn.unity.com/tutorial/as...5484edbc2a37be13b51e#5efba504edbc2a0020903231


    My device:
    - Chrome (latest version)
    - Max OS X 12.5.1 (Monterey)

    Things I have tried:
    - hard refresh
    - cleared cache
    - cleared site data


    Is this affecting other users, or is it just affecting my machine? I haven't seen any reports of this, feel free to point me at another post if this has already been reported. I'm also not sure if this is the right forum, I couldn't find a Unity website/learn support forum. I also reported the issue in the Unity Hub.

    Try again, it certainly worked for me (I only tried your first link).

    If it fails, try from Incognito mode, or perhaps nuke all your cookies / browser data.

    UPDATE: both of the above links work fine for me, Chrome incognito:

    I'm seeing the same thing on my Mac in Chrome, I have let the Learn team know. I tried Incognito mode too

    Have already tried clearing cookies & all site data and relogging back in. Just tried in Incognito, and videos still don't play, and same error appears in console (also, weirdly now I see two 429 errors)

    429 is supposed to mean "Too Many Requests" but I cannot think how I would have exceeded any rate limit by just watching course videos at a normal pace, so it seems there may be some issue. (Or possibly the 429 is an unrelated issue)

    Notably it isn't even showing a spinner or trying to load the video. Clicking does nothing.
