This has happened to me a bunch, both before and after the latest update.
Often I use LR Mobile to spot check how my photos look on a mobile device, then I go back in to edit. If I do and edit that involves photoshop and saves as a TIF or PSD often I will go back to LR Mobile and see the edited photo just as I expected, but when I save to camera roll an earlier stage in the edit is exported. If I try and change any attributes the image in LR Mobile with switch from the latest edit to the previous edit as soon as a slider is touched.
This seems to happen consistently when I am viewing the TIF or PSD on my phone, then jump back in to photoshop to adjust. After LR desktop syncs the new edit it's in LR Mobile where the issue occurs.
In these situations I've found no solution except to use dropbox to send the final edit to my phone.
