Dear Garmin,
I have contacted the support center without resolving the issue, so I am reporting it here once more. During certain activities such as spearfishing and freediving, even when I select the "heart rate graph" as data in the surface screen, it fails to appear, and only a black screen with void data is shown on the designated page. This is quite frustrating, especially since several updates have been released (including the most recent one from last week), and it appears that Garmin has chosen not to address this matter, despite the fact that we are discussing a premium series watch.
