I have saved several versions of my design. But I can only change the very latest version. How do I open a different version previously saved?
Thanks for the question and the screenshot. In the dialogue box the "up arrow" is the promote command. Promote will make a copy of a previous version and move it to be the latest version. After selecting promote, the versions will refresh with the latest version being a copy of the old version (look for it to be created 1 min ago). At this point, you should be able to click on the Edit command (pencil icon) to open that version.
Let me know if this helps or if you have further questions/concerns. I am looking forward to any feedback you may have.
