I am working in Adobe InDesign CC 2019 14.0.1. When I have a manuscript already flowed into my document and try to adjust the margins on the master page with Adjust Layout enabled, when the new margins are applied to the document, all the existing text boxes "disappear." From what I can tell, they have been resized down to an infinitely small point in the middle of the spread. Obviously, this is not useful. I used to be able to adjust the margins across an entire book-length document in one go with layout adjustment, and the text on every page would be re-fit to the new margins. The attached screenshots show the before and after on a spread (you can see the tiny text box in the middle in the after).
Am I missing a step here, or is this a bug?
Yup, I'm getting this as well. It must be a bug. Adobe, please bring back the old Layout Adjustment!
