Lost Card Data
Scenario 1: My card or journal reverted to an older version without recent edits
Try these steps:
Click the menu in the top-right corner of the card.
Select Version history and check for the correct version.
If you find the right version, click Restore.
If the version isn't listed, your recent edits might not have synced. Check the version history on the device where you originally made those edits.
If the card appears blank with no history:
Use the shortcut Ctrl/Cmd + O to search for your content—it might be in another card.
If these steps don't resolve your issue, please contact support.
Scenario 2: Edits made on one device aren't appearing on another, despite both showing as synced
If this happens, it is possible that one of your devices encountered a sync issue, causing it to mistakenly believe the data was successfully synced.
Try this:
Check the web app: Log in to the web app to see if your data matches.
Compare across devices: If the web version matches Device B but not Device A, then Device A likely has a sync problem.
If inconsistency persists, or the web version is incorrect, please contact support with your details.
Lost Whiteboard Data
Scenario 1: My whiteboard is completely blank, with no cards or content
If you encounter this issue, please refer to the guide: "I can enter my whiteboard, but I can't find anything!"
Scenario 2: My whiteboard content, layout, or connections reverted to an older version
Try these steps:
Click the menu in the top-right corner of the whiteboard.
Select Version history and look for the correct version.
If found, click Restore.
If you can't find the correct version, please contact support, and we'll help you quickly.
