Use versions and resolve save conflicts

Follow the steps

1. 1

   Save a changed canvas. Successful content saves create a numbered board revision and preserve a version record.

2. 2

   Open the canvas toolbar and choose Version history to list saved versions with their revision and timestamp.

3. 3

   If the current editor is clean, choose Restore beside an earlier version. Canvas Perch writes that content as a new current revision.

4. 4

   If a save reports a conflict, choose Download my draft, then Load latest version. Reapply the draft content deliberately and save again.

What to know

• The content save includes the revision that was loaded. The server uses a conditional update and returns a conflict instead of overwriting a newer board.
• Restoring a version keeps the history and increments the current revision. It does not erase the version you restored from.
• The editor also keeps unsaved changes in local storage for the signed-in user and board when possible.

Troubleshooting

• If Version history is empty, save the canvas once. The initial board may have only its creation state.
• If Restore is disabled, save or download the current draft first, and confirm that your board role is not viewer.
• If the same conflict repeats, refresh the latest board before making another batch of edits and avoid saving two stale tabs at once.
