Thanks, but within that drop-down there doesn't seem to be a "pause" function for syncing for me, only for Address Lookup (GPS) and face recognition indexing. The only other option I see is "Sync with LR mobile" which if clicked upon takes you to an Adobe sign-in page.
This might be off-topic, but why would GPS and face recognition functions be in the same UI/dialog as LR mobile sync anyway? They could be (or are) unrelated functions for a lot of people's workflows. I'm sure there are users who want to sync but not use GPS or face recognition functions, and vice versa. This is like opening a dictionary- you start in one place and it takes you somewhere else, and then....
