The mobile app released on 2023/02/27 introduced a new API for viewing videos was introduced.
But this API was not available to Guest accounts.
This prevented the Guest account from viewing videos when using the affected version of the app.


When we deploy a new API or change the way it is used, we will make sure to test for privileges to avoid similar errors in the future.
