I'm facing an issue with Firebase dynamic links on iOS . When I send the link via an gmail (HTML hyperlink) , the email gets appended by a urldefence.proofpoint domain to protect the URL most likely . But this causes an issue in the way universal links work . Proofpoint redirects me to the original url after validating the url eventually , but Safari does not open the app at this time . It tries to go to the fallback url . Anyone have any ideas .?
