The Insider Episode 111: November 19, 2021 does load for me.
Your link appears to be going through your districts SafeLinks protection through outlook.

Some resources are publicly accessible on PowerSchool Community while others are available to specific roles in a district such as the role of a Designated Support Contact(Technical Contact) or users with a PowerSource account.

If this is something you feel you should have access to, we recommend working with one of the Designated Support Contact from your school or district, who can review your access.
