Hello,

Thank you for reaching out!

Unfortunately in MacOS platform the devices using DisplayLink technology do not support HDCP.

Streaming services like iTunes, HBO, Amazon Prime, Netflix or Disney+, YouTube TV, Udemy etc. are using HDCP protected content. Which means that they will not work. This is currently one of the DisplayLink limitations.

In those cases the video would remain black while audio is still playing. Please take a look at this article: Content protected video does not play on Mac while DisplayLink screens are connected

Due to limitation on our end it is expected that this feature does not work. We get feedback from many users that it is worth checking other browsers, many that were using Chrome have success with Firefox now. I hear that also changing the hardware acceleration settings in the browser helps.

If it was working for you then it is possible that the browser was allowing the content to be played even though there was the limitation and with the new update they updated their policy.

Unfortunately I cannot suggest any other workarounds as this was never meant to work.
