Hello,
In the past, on the working revision you had a button called "Revert" to retrieve your working revision as it was when the previous revision were released and the working created. But since few weeks, I do not see this button anymore. Perhaps it was removed. I need to read the release notes.
With the "Change Log" tab you can track what you have done to do manually the work.
Note: when you do your tests, you must go to the sandbox tenant and if you want to copy your production data and configuration to your sandbox, you just need to create an IT ticket to Autodesk and they do the update in few days maximum. They are very fast.
