Garmin has finally finished up v21.xx beta development for the Fenix 7 and Fenix 7 Pro. Also rolling out from today globally for the Enduro 2, Epix 2, Tactix 7 and other smartwatches, System Software 21.19 introduces dozens of new features, bug fixes and other improvements, including support for breathing variation insights from the new Forerunner 570 and Forerunner 970.https://www.notebookcheck.net/Garmin-releases-major-new-update-to-older-high-end-smartwatch-with-new-sleep-feature.1022383.0.html
I just tried to do the update on my Epix Pro gen 2 and it fails at the very end to install. I even tried the Garmin Express software update route plugged into my computer and it also failed. I don't think this update is ready for prime time for the Epix 2.
Mine EPIX PRO 2 updated fine over wifi. It was showing update available, I approved it, and it went well, with auto restart afterwards. What I noticed though was a huge volume increase on voice alerts during activity. I didn't had the phone with me to adjust that and had to bare with it for almost two hours. I hope things fixed will make this update useful.
