When viewing and downloading renders from the gallery, if a 'group' of renders (see image attached) has been expanded at any point, backing out and clicking on a single render will not bring up the render preview popup - even after closing any open render preview popups (clicking will simply do nothing).
As a workaround, you must close and re-open the design file. Go back to the render workspace and select only the single render, without clicking on any groups.
This is repeatable as it happens every time (for me, at least).
Thanks for reporting this issue! I was able to reproduce this on my own file as well. I can document this for our development teams to investigate.
