Answer 1

This is an expected behaviour where Apple prompts the user first time if to open the app. Only if universal links are implemented, it does not ask for the second time. Our AASA validator tool (https://branch.io/resources/aasa-validator/) shows the AASA file to validated correctly but while testing on the install page of your redirected website, it is showing a 404 error. So, we are unable to replicate this on our end to check further.

Could you please share your app store link so as to help us out here.

Also, would request to check our documentation here ( https://help.branch.io/developers-hub/docs/ios-troubleshooting#section-validate-if-aasa-file-successfully-downloaded ) so as to confirm if the device is receiving the generated AASA files. This is a known issue with Apple for iOS 13.x+ where the AASA files do not get ingested into the device and causes the link redirection to show a prompt or a fail.
