CC 21.2.0 File > Place Embedded works differently ?
Just upgraded to the June release of CC2020.
I have an issue when using File > Place Embedded to import a .png asset into a design. If I open the Smart Object Layer and add a new Layer within it, Photoshop throws a warning error when I try to save it back to the project:

The document tab for the Edit Contents Window is a .png, rather than .psb that I'm used to seeing, hence the issue with saving it when I've added a Layer. In previous versions, when the embedded object was converted to a .psb I could toss as many Layers into it as needed, which was really useful.
Is this just a new feature change or an issue that is noted ?
