I've reported this issue 5 months ago and back then the ticket was created, but it wasn't resolved in Beta, and we didn't get the update since then.
So I'm posting it here in hope to get attention. Just check the video to see how animation is jittery on new Fenix 8 and how smooth on old Fenix 6, it's quite annoying especially in activity like breathwork...
Below I'll post the URLs for threads with the reports. Can we please have an update about this bug?
