Question:

When clicking an Engage Invitation Link from an email client on an iPad, why doesn't the Engage App open?

Answer:

Enterprise Email Domains frequently employ the use of Automated Link Inspection Software such as URLDefense or Symantec to verify the link being clicked isn't malicious or otherwise invalid. This software will route the normal linking traffic away from the intended Engage Link which breaks the Universal Deep Linking functionality employed by Apple which is used to trigger the automatic opening of the Engage Application. 

To resolve this issue the security software in place must be disabled or reconfigured in a way which allows for the links to be opened in the proper application. This must be handled by the IT or Network team of the customer as we cannot know what security standards are in place on their end. Otherwise, users will need to manually enter the Engage Meeting Information provided in the email.

At this time the Yahoo iPad Application is unsupported due to how the app handles external links. The Gmail and Outlook iPad Applications support this feature, though Popups will need to be enabled and a clearing of the local Safari Cache will need to be performed to ensure comparability. This can be cleared by navigating to Settings ->General -> Safari.
