In recent versions of Pro it seems that editing behaviour was changed to not show edited geometry where the edited layer is being projected - i.e. it is in a different coordinate system to the map itself.
Behaviour:
Make a dataset editable. Select an item. Edit the vertices. Press F2. Old geometry shows again. Save the edit and refresh screen. New geometry is shown.
Please revert this back to ArcMap / earlier Pro behaviour where you can edit items while being projected.
Add a warning if you have to.
In my case it is often when I have geometry in GDA 2020 and have the map in an MGA projection of GDA2020 (e.g. GDA2020 MGA zone 55). I don't often mix datums while editing so have not tested that aspect yet.
