Accessing my Cloud Certification Bundle Videos

I just purchased the Complete Cloud Security Bundle and as I manuever around the AZ-900: Microsoft Azure Fundamentals Certification - 2022 Slideshows, the video won’t play on the website-- I have to download it. When I downloaded the Introduction video, it worked and I was able to watch it on my Windows Media Player. When I download the rest of the videos after that, the videos wouldn’t play. Can someone please advise me on what’s going on? Thanks in advance.

Hi,
I got the same experiences as yours previously.
You may try to change to use the different browser (like Brave), without any addition Extensions installed like AdBlocker etc. Alternatively, you may try to access it through tablet or mobile phone, or different OS.
Based on your description, I just manage to suspect this is caused by the browser itself.
Hope you could find the solution soon.
