Diagram feature broke my board

Hi ​@Chrissy Papanicolas, thanks for reaching out!

To help us better understand what happened, could you share a bit more detail? For example:

• Which steps did you take right before noticing the content was removed (e.g., converting shapes to Diagram, applying a template, etc.)?

• Was all of the affected content created before you tried the Diagramming feature, or was some added after?

• Does the same issue happen if you try to reproduce it on a new board?

• Are you working in the browser or desktop app (and which version/browser)?

If possible, could you also provide a screenshot or short screen recording showing what your board looks like after the issue occurs?

This will help us narrow down whether this was an unexpected bug with the Diagramming feature or if something else might be happening.

Hi, I was able to revert using the version history (not the Undo button as initially attempted). 

It’s an existing board with content (BPMN diagramming shapes) which was all created before. I tried the new Diagramming feature and it removed the swimlanes and some of the other shapes (activities, decision gates).

I was working in the Edge browser. 

Hi ​@Chrissy Papanicolas, thank you so much for following up and sharing these details!

I’m glad to hear you were able to restore your work through version history. From what you’ve described, it sounds like the issue may be connected to the new Diagramming feature interacting with existing BPMN shapes (like swimlanes, activities, and decision gates).

In the meantime, if you happen to encounter this again, could you please grab a quick screen recording or screenshot before reverting? That would be super helpful in narrowing down what’s happening.

Thanks again for taking the time to report this!
