Problem: When looking at Revision History in Workflows, Custom Code modules are not retained - it currently always shows whatever the current custom code is.
From my perspective, this is a huge hole and folks are not going to know about it until/unless they find out the hard way (like I did). I made a significant change that I needed to revert and was not able to go back to the previous version.
I was told by the helpdesk “I’ve just connected with our internal team who was able to confirm that currently the workflows tool is working as expected. In other words, the revision history only showing the current custom code is a known product limitation at the moment. We’ve looped in the product team and this limitation is on their radar, but at this point I do not have any other concrete details on when that feature of the tool might be updated.”
