T-Rex 3 Pro navigation completely broken when waypoints are set
Hello,
I want to share some photos with the same route in my Garmin Fenix 8 and my Amazfit T-Rex 3 Pro.
There's a critical bug with the navigation that makes it unusable when waypoints are set and/or you repeat parts of the track.
As you can see the Garmin Fenix 8 notifies perfectly not only the left and right turns, but the U turns and the forks. The T-Rex 3 Pro is a completely disaster and unusable.

Right turn Fenix 8 and T-Rex 3 Pro
It was also very well detailed here. Now tested with a Fenix 8 side by side:

u/Amazfit-Bryce can you report this? I have also uploaded the data in Zepp.
Stopping to take these photos, meant to break my training, but I though it was worth the effort. I hope you can solve it.
