I have an e-commerce website (+ native mobile app) and redirect my mobile app's users to the website through the in-app browser; for pages like "About us" or "T&C". But some of the users continue purchasing products on the in-app browser, whereas I would like to redirect them back into the mobile app. How can I recognize whether a particular user has come to this page from the native app or already been? Shall I design two separate mobile views for each of them?
EDITED:
Mobile OS = android
Server = .NET core
Website = vue.js
