I have the version 4.54, in android 11. The e-mail is sent but clicking in the link the track is only drawn for the very first km of the activity. This happens since some weeks ago
The total activity is actually well recorded,
if afterthat you check it in garmin connect. The problem should be with the server or program that is dealing with the track visualisation in the e-mail link
This is a big issue, as it's a critical safety feature that does not work
