Course not loading on macOS Safari

Hello,

After the recent macOS update, our courses no longer work when using Safari on Mac. Safari on mobile devices work without issue but the Mac Safari version doesn't. No issue with Chrome or Firefox on macOS, only Safari.

It specifically happens before playing a video and sometimes when launching a course. Even if the video is extremely small in MB size and the course is 1 or 2 slides, doesn't matter, as we've test different variations and nothing works.

Testing was done within our LMS environment, on SCORM Cloud and pop-up blocker was disabled.

However, it doesn't work as the video file we used when testing is very small. Once the course reaches a .mp4 file, it stops working. Prior to the recent update, our courses worked but now they don't. Multiple colleagues in different locations are reporting the same issue as well.

Again, no issue with the iPhone or iPad versions but has anyone else experience this issue with the latest version of macOS and Safari?
