The same messages that DO SHOW the issue only show it in Mail.app on macOS & iOS when the gsuite user account is setup as 'Google' vs. Sending a message from an external account into a gsuite account user DOES SHOW the issue (this might be tied to admin settings in G Suite > Settings for Gmail > Safety - still needs to be tested more) Sending a message from a gsuite account user to another gsuite user in the same account DOES NOT show the issue
Sending a message from an internal gsuite account user to another user in the same gsuite account + another user outside of the gsuite account DOES show the issue Sending a message from a gsuite account user to an external party DOES NOT show the issue The same messages viewed in or in Mail.app on macOS or iOS with the account type set to 'IMAP' have their links left untouched. This seems to be the real pickle as all the following use cases below require this to be true for the link manipulation to occur. The issue only appears to surface under specific use cases and always requires the user to have setup Mail.app on macOS or iOS with the gsuite account/user set to type 'Google' vs.
Google says it's an Apple issue and Apple says it's a Google issue. I can and have reproduced this for over a week now and have been hammering google & apple to fix it with no luck.
