if we are showing the products in 3 different recommendation (eg: recommended for you, based on your last purchase, etc) to the logged-in user (A) on the homepage/landing page on m web, and if the same user logs in to the app, Target should be able to identify the user as user (A) and the user should see the same products is recommended for you, based on your last purchase, etc as he saw on m web.
how this can be achieved?
