V1.11 - vision yaw fusion

I am using quadcopter in indoor environment (motion capture). Just upgraded to v1.11.0
The issue I encounter: when drone is powered on or rebooted facing southbound, it refuses to receive vision yaw (heading rotates 360 deg and takeoff is rejected due to yaw estimate error).
In v1.10 it worked well
I use the following parameters :
EKF2_AID_MASK 24 (vision position and yaw fusion)
EKF2_HGT_MODE 3 (vision height fusion)
EKF2_MAG_TYPE 5 (none)
Something I have to change?
