See my longer replies in the thread, I've tested this extensively and can reproduce it reliably. Please report this to google to help back my claim which they of course are casting doubts on left right and center.
Can you confirm you account is actually set to "IMAP" and not "Google" in macOS? See my other comments in the thread where this only happens for me under that condition. Downloading the messages via pure IMAP produces unmodified links.
I can confirm this has nothing to do with that as I do not have it enabled on my account and can reliably reproduce the issue. See my other replies in the thread for more details.
I can and have reproduced this for over a week now and have been hammering google & apple to fix it with no luck. Google says it's an Apple issue and Apple says it's a Google issue. 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. "IMAP". 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 same messages viewed in gmail.com or in Mail.app on macOS or iOS with the account type set to "IMAP" have their links left untouched.
- Sending a message from a gsuite account user to an external party 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 another gsuite user in the same account DOES NOT show the issue
- 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)
- 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. "IMAP". It DOES NOT show up in the GMAIL iOS app nor does it show up in the gmail.com web interface.
Google support has been effectively useless. Apple support has honestly done more to shed light on the issue. However, both companies are blaming the other and refusing to escalate to engineering or get on a call with the other company to sort this out together. Of course, Google support claims nobody else is reporting this, while Apple support alerted me to this thread. Super frustrating all around. If you are a Gsuite user please report this so I'm not yelling into the wind here. I can also confirm for my account the issue started on October 6, 2020.

I've got 2 clients using them and wish I could say this info surprised me, but they are a terrible registrar & DNS provider. I've asked both of my clients to reach out to them about the issue but don't have any information past that.
