This conversation has been merged. Please reference the main conversation: Photoshop CC 2018: Do you plan to include Device Preview?
I've tried Skala View as well as (literally) ALL of the alternatives. They do not work properly. I understand that you're trying to focus on what you believe is important to Photoshop and that a preview has been moved to XD, which you probably prefer me to use, but most of my work requires a lot of photo manipulation and other effects and features not included in XD. Having to work with BOTH applications is a bad workflow.
As a workaround, I end up using PS2017 so that I can use Device Preview. But then I'm left out of all the new functions and features included in PS v20+.
