Fenix 6 Pro - Cycling Navigation

HI All,

I have a Fenix 6 PRO and I have an issue when trying to navigate routes created on Garmin Connect.

Let me list the steps:

1) Create the Route/map (Cycling map over 60Km)

2) Importing map on my F6PRO

3) Starting Cycling activity and navigating Map

4) Activity stuck on "calculating"

PS: I have no issues on navigating Wikilocs routes and no issue on the calculating step

Can you please advise, how I can create my own route and navigate them on my watch without issue on calculating the route? What do I do wrong?

Thanks

Simone
