turns layer missing from tile service

[RegularnaMatrica]

I'm interested in finding intersections and possible maneuvers at intersections. Documentation says that tile service returns turns layer containing that information. After I transform longitude and latitude inputs as in documentation and use read_mvt_data function from protolite package in R I don't get turns layer. What I get is 3 things:

1. speed layer (as in documentation)
2. osm id for intersections
3. internal-nodes (don't know what that is)

Did someone have similar problem? Does this happen in python? Is it due to protolite package? Is documentation on tile service misleading?
