Issues flying the SR22 with DFC90 using an IFD X-PLane on iPad

[Gremlin]

I've tried this in both X-Plane 11 and X-Plane 12 with similar results, I was flying the plane from KPAE to KAWO using the RNAV 34 starting at Savoy, I noticed several oddities, I think some are expected not sure about others, not sure if the issue is with the plane sim or the IFD X-Plane simulator app

 

1) The plane does seem to follow the flight plan on the IFD but you seem to need the DFC90 in GPSS not Nav mode, it managed to fly to the procedure turn and execute it

2) The PFD doesn't show the correct next destination when tracking GPS 1

3) When the plane starts to go into the approach you seem to have to manually press approach, on the DFC90

4) The glide slope shows, but before capture the plane just clicks AP off, and won't allow you turn it back on and it basically just goes haywire.

 

Has anyone else seen these issues?
