Open an existing Canvas during an activity meeting to review the artwork together or make changes in context. The meeting uses the same space-owned file, so saved changes remain available after the call.
Before You Begin
Live apps are available in supported activity meetings, not direct-message calls. Participants still need access to the Canvas and its owning area; opening it on stage does not grant file access.
Use an existing Canvas when possible. Creating one requires Canvas app access, Coordinator access, and an eligible destination area. If the artwork needs preparation, follow Create, save, and reopen Canvas artwork before the meeting.
Open the Artwork on Stage
Other participants can select the Canvas feed as they would another feed in the meeting. Check that everyone who needs to contribute can access the same document.
Choose Canvas from the meeting's Live Apps picker before browsing the activity's accessible files.
Review and Edit Together
Canvas can share layer edits and live pixel changes while people keep their own workspace view. Pointers help the group indicate where they are working. For a review, one person can make the requested adjustments while others discuss the result; for parallel work, agree which layers or areas each editor will handle.
Avoid simultaneous painting over the same pixels. Later changes can replace earlier ones in an overlapping region. Live collaboration does not guarantee that two different treatments of the same area will both survive.
Finish With a Confirmed Save
Choose More > Save when the review changes are complete and wait for the save result. Routine autosave collects changes before saving; a participant seeing a live stroke is not proof that the online saved copy is complete.
If saving is delayed or the connection is recovering, keep the browser and artwork available while the issue settles. Follow Saving and sharing for local recovery and fresh-device verification.
Leaving the meeting does not delete the saved Canvas. Reopen it from its owning area, Docs, or an accessible document link to continue later.
If the File Is Unavailable
Check that the meeting belongs to an activity, then confirm the owning area and private-area membership. A missing creation action can reflect Canvas or Coordinator access. If the editor reports an opening failure, use its retry or browse action rather than treating an incomplete load as missing artwork.
Return to Canvas for the editor overview, or Saving and sharing for the collaboration and access boundaries.
