I am trying to implement a feature like in this question Android Deep linking: Use the same link for the app and the play store but for iOS app. Currently, my app uses UniversalLink(example: https://www.example/com/code/000000), and if the app doesn't install server redirect to the App Store by link (https://apps.apple.com/us/app/instagram/id389801252 - for example) but how then after installation open link inside the app? From this info https://support.google.com/authorizedbuyers/answer/6167336?hl=en I understand that need some reference like (https://apps.apple.com/us/app/instagram/id389801252?mt=000000) what is ?mt=0000 <- this is deep link or something else?
How to implement this algorithm
