With the automatic Zoom integration, you won't need to manually update your live stream URL - see here to set this up.
If you are not using the Zoom integration, or you are using an alternative live streaming platform, you will need to manually update your live stream URLs on your Portal.
If you have a single URL that never changes, you can update this link from the Activities section of your portal. Head to 'Activities', and click 'Edit' of the activity you'd like to amend. Scroll down to the live stream section underneath the timetable, ensure 'Live Stream Only' is selected and then copy and paste your live stream URL into this box. Click 'Approve' when you're finished.
Important note: you must only copy and paste the live stream URL into this box - anything additional will cause your live stream URL to be invalid and your members will not be able to join the class. See below for examples:
If each class has a unique URL, go to the 'Classes' section of your portal, copy and paste the live stream URL into the corresponding class' 'Live Stream URL' box, and click 'Update Live Stream' to save. You'll need to do this for each class individually.
