Some users may be experiencing an issue with embedded Panopto videos on myPortfolio or Space pages where they are asked to log-in before viewing, sometimes in a non-resolving loop. This issue is caused by the browser blocking certain cookies/cross-site tracking.
To resolve this in Safari, click through Safari > Preferences > Privacy > then un-check ‘Prevent cross-site tracking’.
The AV team have made a video walkthrough on this issue that you can view here on Panopto, and have also provided screenshots on how to fix this issue on this help page on Space.
Panopto have also published instructions on how to resolve the issue, which can be found on their website.
