Is it possible to right mouse click in a web map, select "What's here?" and have the reverse geocode present the reverse geocode results from 2 or more organisation locator services?
We've set up What3Words, which is great for field workers needing to populate these values or navigate to w3w locations, but it looks like an organisation default locator (the one at the top of the list in the org settings) is the only one that a) pulls into field maps, and b) is used for reverse geocoding in a webmap or field map.
From my limited investigations, it looks like the current workaround is to have custom locators (and a world address locator "view") and then use custom group sharing of these to restrict locator access to various users. Not a solution, but a clunky workaround.
