jaknudsen Paul Bullock - Please file a support ticket for this issue if it's still happening. If support can't figure it out they'll escalate it up to us in the product group for investigation and we can have the right on call team investigate.

I'm assuming this is happening on a regular basis and not after leaving a page open for a long time? (Stream thumbnail URLs have a time to live on them, so I could see this maybe happening if the page was left open for a long time or something.)

Thanks for the reply. We are still experiencing the issue on a regular basis, but it seems to be limited to Safari browser. I wonder if this issue is related? https://techcommunity.microsoft.com/t5/microsoft-stream-forum/stream-embed-not-visible-webpart-is-blank-in-ios-on-mobile/m-p/290034/highlight/false#M2670

Where du you suggest I file a support ticket?

jaknudsen Is your issue on the web using Safari? Or in the SP Mobile app itself on iOS?

    jaknudsen - I talked with one of the engineers and it seems like this is related to Safari blocking cross site cookies that are needed for the thumbnail to render. You could try changing those settings in Safari and see if that addresses it. If not you could file a support ticket so that support engineers could get traces/logs from your exact issue.
