It would be useful to be able to geo-tag photos for Facebook and Instagram. As a destination hotel representative, a lot of people search for a location to see feeds, and I would appreciate that being something that I can incorporate in my scheduling to make posting more streamlined.
We have now shipped the ability to add Geo Tags (and People Tagging) to IG posts!
One restriction is they have to be scheduled as "auto-publish", as this will only work going through the new Instagram API.
Hope this feature helps!
