Like previous versions of InDesign CC the color separations preview still does not work correctly.
When user tries to view separations by turning a color separation off, or toggling back and forth between colors, the visible page in the document goes completely haywire - scattering elements and superimposing images from other nearby pages. See attached screenshots of the issue.
This has been an issue for awhile and I am dismayed it still has not been addressed as it is a very useful function in the printing industry. Since the launch of CC I have had to check my separations in Acrobat and then re-enter InDesign to make any corrections. In previous versions it used to work correctly.

I'm having this issue too. Big time irritating. Also just started happening when I upgraded to the iMac Retina 5k, 27in, 2019 running 10.15.3 OSx and Version 15.0.1 of InDesign. The attached is just one sample when I turned black off.
How about you post the solution here?

Simply put Separation Preview DOES NOT WORK CORRECTLY. Try it out yourself and find out.
Does not matter what OS you are using. High Sierra, Sierra, Yosemite, etc. Separation Preview has not worked correctly since the CC launch.
