Hi all,

So I’d make a distinction between Play and Edit modes. - Take a look at what your settings are when you click the 3 dots next to ‘Launch Session’

My workflow - I have ‘Auto Start Game’ enabled.

I click ‘Launch Session’ → Wait a painfully long time for everything to upload/launch → Press ‘ESC’ and “End game” → You’ll now be in Edit mode and see your memory bar above you. → Back in Editor, the Memory Calculation should be clickable. - When you do the Memory Calculation, it will create a private version at the same time, So I just do a Memory Calculation to create private versions.
