What causes this issue
Zencastr is a large application and has system requirements in order to access it.
A blank page or page stuck on loading can happen when:
The host or guest has a slow or unstable internet connection.

The host or guest has browser security extensions installed that block Zencastr.
The host or guest has an ad or script blocker installed that blocks Zencastr.
The host or guest is connecting from a network that has strict security settings (e.g. a company, university, hotel) that blocks Zencastr.

Step two: refresh the page
