Vehicle doesn't switch to guided mode for the purpose of mission planning

Is there any update related to guided mode for mission planning in QGC? I can switch from manual to stabilise mode and vice versa but cannot switch to guided mode in the QGroundControl interface. GPS is connected to my BlueROV2. And Guided mode has been set to “ON”, however control doesn’t switch to guided mode. Hence, the ROV doesn’t follow the trajectory in the mission plan. I receive this error:

“Unable to start mission: Vehicle failed to change to Guided mode”
