Export for Screens: pre-export settings for PNG and JPG are same, but post-export JPG resolutions vary
This is odd. I'm in Illustrator 2020 (24.0.1).
I have a .ai doc open.
I go to File->Export->Export for Screens...
Under the Artboards tab, I set up PNGs and JPG 100s, at various scales using Width as the variable. (See Export for Screens Screenshot)
I hit the Export Artboard button, and am notified of success.
I go to Bridge to examine the results. (See Adobe Bridge Screenshot)
The exported PNGs all have resolutions of 72 ppi (expected, good result).
The exported JPGs have varying resolutions, from 12 to 72 ppi (unexpected, bad result).
Why would that happen? Why don't all the JPGs have 72 ppi resolutions, while the PNGs do?
