@Dimitrios-Kanellopoulos cool.
Thanks for mentioning steps to reproduce. In fact - I did turn off hr belt as the watch was struggling to lock on to my hr with ohr (which never happens) so I thought maybe it stubbornly wants to connect to hr belt which was impossible at that time. Only after that I thought meh to hell with hr, it’ll figure it out anyway sooner or later and I proceeded to load the route.
