Live track link doesn't work (BUG) > Fixed (Resolution << Ref: 22665795K1 >> <Q#:1000352>)

Did you also try forwarding the message to yourself, as advised in the document, too?

Having the exact same issue. Garmin wanted my wife to contact support and they would get some data from her device that they thought would help, though I doubt it. The link is just non-existent. No amount of forwarding or shuffling the email around works. Emails from 8/3/22 worked, Emails this week didn't. If they were sent from Garmin in working order, which they haven't been able to confirm to me, then Gmail is neutralizing them and erasing all the links to make the button just a graphic, and no amount of clicking it's safe does anything. We've started multiple short workouts sending notifications back and forth to each other and none of them work, and every email is flagged by gmail as dangerous.

If you are tapping the "looks safe" button from the Gmail app, try doing it from a browser on a PC instead (a browser on the phone may work too). It looks like an issue with the Gmail app. At least that's what is the conclusion of this thread (scroll down to the last post): Email links still unclickable after clicking "looks safe" on suspicious email - Gmail Community (google.com)

I have clicked looks safe from gmail and from chrome with no change yet. Refreshing the page didn't seem to change anything. Haven't tried the spam and then telling it it's not spam. The 'dangerous' email warning is definitely different than spam, this is the first time in a long time I can remember seeing that warning in my gmail.

Try also right-clicking the button, and opening from the context menu. There may be additionally an issue with a popup blocker of the browser, some plugin, or an anti-virus.

After you have clicked the "looks safe" button in a browser, select from the message menu (the triple-dot symbol up right), the option "Show original" and search the string "livetrack.garmin". If it is there, the link is in the email, and probably blocked by a popup blocker. Also try another browser, whether it makes any difference.

While Gmail is the one doing the suspicious email blocking, Garmin is not helping the process.  If you read Google's Bulk Sender Guidelines (https://support.google.com/mail/answer/81126), there are a couple things that Garmin is absolutely doing wrong.

1. The URL is masked / hidden behind a button when, but the guideline states: "Links in the body messages should be visible and easy to understand. Recipients should know where they go when they click links."
2. The emails are unsolicited from the recipient's perspective.  We added their email to Garmin Connect, and now they get some spam every time we work out.  While there is a link to Garmin support, there isn't a clearly described unsubscribe process for our friends and family to opt out of receiving these.  The guidelines have a whole section on unsubscribing, with the first recommendation: "Include a prominent link in the message that takes recipients to a page for unsubscribing."

Those were just two examples, but Gmail's filters take all of these things in aggregate when deciding if emails should be flagged.  While Garmin appears to be meeting many of the email server and internal header guidelines, the content of the message is pretty bad. 

Happens no matter the location (work, home, ipad). Its a gmail thing for sure

I'm looking at the message source in Gmail and it's obviously kilobytes of crap. Even those old emails where links worked don't actually contain the link in the message body. How does this stuff work anymore? Why can't Garmin send and email in a plain text format instead of html with just a few words and a link in it?

As a test, I added @yahoo.com email and the link in there works just fine.
