It sounds like you are reporting different issues.
In terms of manual trimming, I'm not aware of any changes that we've made that would affect that. There is currently an issue which prevents the stab trim wheel from being clicked and dragged but that has no impact on the elevator trim assignments. We've flown a lot of flights here without any trim issues.
Regarding being out of trim when disconnecting the AP, we reworked the autotrim logic in v1.2, and all of our testing here results in the aircraft being perfectly in trim when disconnecting the AP. That's a significant improvement on the previous behaviour.
I'd recommend that you both submit support tickets so that we can get some more information, including hardware and control assignments.
