THE ISSUE - Hi there guys we have been through documentation and gone back and forth on forums and we can not get universal links / Deep link to work for us. OUR SETUP - We are running Flutter and are looking to post images from the Gallery into the app only issue is it does not pick up the page its meant to open once the share button is clicked. We have tired all the steps meticulously and still can not get it to work. Are they any known issues with this ?
