Here+ RTK (Hex) support for Rover

Hi
Here+ RTK is included in copter and planes later releases, Im using a rover application and tested rtk float fine with copter 3.5 on temporary handheld cardboard. Rover 3.1.2 seems not supporting RTK here+.
Anyone knowing about latest rover beta is supporting rtk Here+?
Regards Magnus

Interesting question
I hope someone could answer it
