ACR 13.2.0.738
Mac OS 11.2.3
To replicate:
1) Open 5 images in ACR
2) Select the crop tool (c) and crop an image
3) Select edit (e)
4) Select zoom, fit in view.
5) Check global zoom settings
6) Select next image
7) Select previous image
8) Reselect next image
9) Select previous image
10) Note how zoom setting changes from "fit" to whatever the zoom setting is for the cropped image.
This is a bug. ACR 13.1 did not do this. ACR 13.1 "retained" the "fit in view" setting regardless if an image was cropped or not when selected and the view setting was "fit in view" and "global zoom settings" was checked.
