Hi, Its 11th November, 43.10 latest version loaded, still get the error in Creator Portal, no errors in UEFN log. The workaround as above is still same click “Calculate” and the Publishing Pop up on UEFN screen occurs.

This was a launch to Android Phone (Samsung Galaxy 10)

if you have NOT clicked “Calculate” then no Memory Calculation and no publish pop up.

The documentation needs updating in GREEN if this is the new way in the attached Word document following this works without error
