It looks like X-Acquire only does backup and restore of settings with the X100V. In the X100V manual it states "This camera does not support tethered photography" next to both X Acquire and Capture One.
Too bad I liked the feature with the X-S10. It wasn't perfect using a folder for it to drop pics into and Lightroom/Capture One to watch and pull them form, but it was better than nothing.
