@DTS Engineer I have now moved the file into the .well-known folder and it now lies here: https://staging.docyt.com/.well-known/apple-app-site-association Still the universal links are not opening the app. Before you ask, i have already done the following: reinstalled the app from TestFlight restarted the phone

@DTS Engineer How then does this work when the app is installed via XCode ?

How then does this work when the build is installed via XCode?

This is the answer that solved my issue. Thanks
