Please, please do not do this.
I've had it for at least several days now and it is the most annoying thing. The layout of the standard garmin home screen was fine ... don't fix what's not broken.
I was hoping there might be additional training insight, but there is no new information; instead, all the information is harder to locate, and requires an excess of side swiping and searching through to see what was a very efficient, simple, easy to read layout before. I was just going to turn off the beta but I'm afraid this will be coming out as the standard format soon and feel compelled to voice my very strong objections.
If you're going to change anything make it easier to see more training insight. The garmin watch is supposed to be able to sense what swim strokes youre doing, but it gives no information on that for my swim workouts (because i switch between several strokes through my swims, and it seems that information should be viewable if it is advertised that the watch model does this).
Or another improvement I would really appreciate is being able to sync my garmin watch to Zwift for when I'm doing bike trainer rides, because it definitely does not show accurate heart rate while I'm on the bike trainer, and i have to have another brand chest strap hr monitor to incorporate heart rate data for my rides in watopia.
But the garmin app homescreen was something which I had never even considered as needing improvement, and now that the beta has made me think about it, I really appreciate the old home screen much more. Please don't change it, or at least don't do anything as drastic and cumbersome as the beta layout.
