Currently as of 10/12/20, Zoom does not respect multiple Portal user profiles.

Zoom will stay persistently logged in across any user profile that is currently using the Portal.

For example,

Portal User A is logged into the Zoom App using User A's own Zoom credentials.

Portal User B clicks on the Zoom App in Portal User B's installed app list.

Zoom User A will be shown as signed-in.

NOTE: In order for Portal User B to use their own Zoom account, Portal User A has to sign-out.

This is a major security concern! Applications are able to share data across user profiles.

Please address this ASAP.
