It's a similar for me. I'm running the PC version, streamed in SU6 on the GeForce Now platform.
The plane responds well to elevator trim inputs in flight, however, according to the MSFS cockpit/external HUD the useable range is about 5% up or down which equates to 0.25 degrees up and 0.75 degrees down. To get the trim through the full range takes around 200 seconds - I think this has been mentioned before.
According to the HUD, -2% if fine for level flight at FL160, 450 KIAS without external stores of any kind.
I can share a video if that would help.
