Youtube banner no longer autoplays

Hi,

Since a few weeks We have noticed that our Youtube banner on our site (www.kras.design) does no longer autoplay. We have recently updated but are not sure if this is the reason for this.
We tried to use several different youtube videos randomly but we havn’t been able to solve the issue yet.
Can you help us fix this issue. It must be something simple I guess.

And I just learned that we have the same issue in other browsers like Edge and Safari.
Perhaps it is something in Onetone. Does anyone experience the same or is this just an isolated issue?

Thanks in advance,
Simone
