I flew to two different airports. EKCH and ESSV,
EKCH: After vectors I tried to get established on ILS DME RWY 22R approach.
ESSV: After vectors ILS Z rwy 21.
I switched to LOC but couldn't see CDI.
I got the glideslope but the aircraft couldn't catch it so I could only use it as information for the manual land.
This started in X-plane 11.50b10. I flew many ILS approaches in 11.50b9 without issues.
