PSD files flattened

Hi Alex, 

I'm a seasoned Photoshop user (since v3!) and have recently started working in XD to prototype apps. I was using Sketch. I have to tell you, after I discovered the edit in Photoshop feature, I was elated, only to find out, after editing a 40+ screen app, that every single last one of my layered photoshop files was gone. I mean I searched deep into the temp files directories and nada… I lost over a day's worth of work. It didn't even occur to me that those layers would not be saved, or at the very, very least, a warning would have alerted me to the fact that closing them would flaten them down. To make matters worse, the first time you close them and reopen the layers stay intact, so you conditioned me to think all was working well. This is a massive, massive design blunder. This post was initiated last year. Please prioritize a fix or a warning so other new users to XD don't end up as livid as me. It's enough to make me return to Sketch. The whole point of staying within the Adobe eco-system is features like this that should just work.

So what's the point in having direct PSD support when layers are removed? It's kinda pointless then. The main benefit with native Photoshop document support is seamless workflow cross PS and XD. If the layers are removed the value is substantially reduced. Layers are THE reason I'm using PS. If the purpose of flattening is to reduce filesize then it would be more sensible to make that a manual action for us to apply when the document is finished. Or at least be given the opportunity to store the original layered PSD. I had a bunch of adjustment layers lost when I wanted to edit the file for the second time.
