I have the marketplace version on PC with MSFS 2020. I do have a  Saitek controller too if that helps with anything.

Somehow ended up working the last few times I've tried it this week. I wonder if it had to do with a double binding between the Z key as the MSFS generic AP disconnect, and the CS 717 AP disconnect.

My next issue with this plane, however, is that altitude does not hold appropriately. It holds about 200' above the preset altitude, and this most recent flight that I thought I would give the plane a chance on, it didn't want to hold FL320, it continued to hold 32,200', and so I chose to return to landing to see how it did there.

Next issue: Descending, the plane does not follow assigned VS if I have one set. It holds alright on the climb, but during descent, if I set -2000' VS, it holds -1300' VS or so. If I set it to -3000' VS, it holds -2300' VS. This is another problem that has to do with the autopilot that I can't have.

Next issue: when I was middle clicking the speed hold bug on the descent, it wouldn't show the preset airspeed next to PITCH, as it does on takeoff - climbout. Why not? The speed bug sets appropriately, but the speed on the FMA does not update. This doesn't seem correct.

Next issue: Upon getting vectored to the ILS, I clicked APPR/AUTOLAND, and the AP did not capture the localizer.

Next issue... hopefully last: I bugged 2000' for ILS capture beforehand, and the AP flew right through it, despite the ALT being armed appropriately. The aural annunciations just said "Altitude" as it flashed yellow. I disconnected and handflew this mess to landing. Couldn't disconnect the A/T but I think I read somewhere that that is a key binding that needs to be set up.

Thanks for any help you guys can offer. This plane is a laundry list of issues.

Thank you!
Just to make sure - did you press the NAV button? Do you see magenta NAV on the FMA? 
Have you tried to reproduce this problem without the Saitek?
Also, please try disconnecting the autopilot using the yellow button on the yoke and reconnecting it using the AUTOFLIGHT button in the cockpit.

Thank you for your list. We're gonna try to disprove that.
Same question: what version do you have? CS Store, Marketplace PC or Xbox?

I've realized the issue here has to do with the controller interfering with the autopilot. I use a gyro controller with MSFS. I have a button to switch the gyro off to prevent interference with the AP, and with every other airplane that works fine. With the 717, the AP will not fly the FD at all until I disconnect the controller, which is wired. Connecting it again to land is the next step, and of course MSFS will not recognize the controller once it is reconnected - not until the program is restarted. Which means I can't fly the airplane when it comes time to land.

If the devs could review this particular issue, that would be awesome.

Other items:

I adjusted flight tuning values to more accurately hold VS and altitude with great success. Altitude still holds a little off but it is significantly better. VS holds perfectly in climb/descent.

AP worked pretty well with regards to my last post tonight. I might have just been doing things too quickly and got the flight computer logic all confused last time.
