Incorrect Location using Esri Locator on Instant Apps

[HasanGuler2]

Hi there,

I have an instant app, where users search for an address. Unfortunately, in some cases, Esri's built-in locator displays incorrect location - very different than Google Maps. For instance, if you search for 1 Normanton Road South Croydon, the result is incorrect. Even though I tested the coordinates instead of address itself, the result is still incorrect. You can access the public instant app via the link below. 

tfl.maps.arcgis.com/apps/instant/lookup/index.html?appid=5e6c89776213414f91262efdd9d41234

How can I resolve this issue?  Is there other more reliable and accurate locator API available similar to Google Maps?

Many thanks!

What projection is the basemap in, it looks like it is the grey wgs84 basemap what if your try with a BNG basemap?

I've tried different basemap with BNG projection but the still the same.
