Video not playing embed problem - A setting in your browser is blocking cookies. Mobile only.

Mark_JL we are having the same issue, but in our case we are not using the embed code -- we are using the Stream web part in a Modern SP page. Works fine in Chrome but not in Safari. We get the same symptom.

We tried the workaround suggested in another thread of turning off Prevent Cross-Site Tracking, clearing cache & cookies, etc. but the web part still displays the same message (I have cookie blocking turned off too, and block pop-ups for good measure) -- and prompting to Open in a new window. All our MSFT and Apple versions are current.

Our company has standardized on Apple mobile devices and we are getting ready to roll out our brand new intranet built on SP modern.
