I have a responsive web app(9.1.1) which have the deeplinks in the email templates. If the user opens the email in the desktop and user is able to click directly approve or reject links. But if a user opens the email in the iphone and is not able to approve or reject links. However other links/ normal link to other pages works in the mobile/iphone. Approve and reject buttons resides in the pop up screen. I do understand for ntative apps we may need universal links.But can you confirm do we need any extra coding/plugins or security might be blocking the pop up window? Let us know if anything missed out to be considered. thanks
