Issue Summary Known Workarounds

Users on iOS devices and/or using Safari are receiving an error message: "Sorry your session was expired."

Resolved. This issue was fixed by a Zoom update on June 20th 2021. You may still have to open the Zoom tool in a new tab if you are preventing cross-site tracking (more information for that on Safari on Mac can be found here), but it will work.

Users may get a 300 error message when trying to download Zoom videos from eClass.

Sign into the Zoom website and retry downloading.

Participants do not get automatically assigned into designated breakout rooms.

All participants must be signed into their Zoom vehicle (app, web, etc) prior to launching the Zoom meeting.

iPad Pro, Microsoft Surface (and other tablet/stylus') users annotate a PDF, but overlay stays on screen instead of on specific page.

None available. Zoom has indicated that it is functioning as designed as a temporary overlay to what is on screen that should be cleared when annotating other screens.

Alternative Hosts field is locked (greyed out) when scheduling meetings in eClass under the Zoom activity.

Resolved. Zoom is aware of the issue. Currently, instructors may create Zoom meetings from the external website at and can specify specific alternative hosts. Instructors can also grant co-host access within the meeting in progress.

It is no longer possible to transfer files between participants through the chat panel in meetings.

Resolved. This feature was re-added in the software update April 12th 2020. This feature has been identified as a security concern by Zoom and disabled in the application. Files can be transferred outside of Zoom meetings using the google suite.

Zoom meetings cannot be created through eClass when 10 or more instructors or TAs are enrolled in the course and have accessed Zoom through the tool link. 

Schedule a meeting in (external to eClass), and share the join URL in eClass. Note: Meetings will not show up within the Zoom activity in eClass. Recorded meetings must be shared from to eClass as well.

We have contacted Zoom support about this issue.

Users who have already signed up for a personal Zoom account using their UAlberta CCID email address will encounter an error when they first try to access Zoom through eClass. Once the personal account is deleted, users will be able to create their integrated eClass account.

This help article on the Zoom support portal describes how to delete the pre-existing account.

Alternatively, if users have some critical data stored and do not wish to delete it, you should go to your Zoom account options and change your email address. Then when you access Zoom from eClass, you can generate a new user account with the University license.

Account confirmation emails are not being sent to some users.

This issue has been reported to Zoom. Contact eClass support and we can re-send the email.

Some users have difficulty connecting audio to zoom meetings on mac devices.

Rebooting the computer solves the issue. Participants should always run through the Audio/Video check before entering a meeting.
