AIRBUS A350-1000 Auto pilot issues

Device: iPhone SE (2nd Generation) iOS 26.5

I noticed every time I’m in final within the glide slope (2,000ft altitude) on both the open beta and actual game, the auto pilot is not registering and have the aircraft slowly descending too fast. Unfortunately I do not have the ability to do a screenshot when the aircraft does a nosedive and I lose my entire flight after it crashes. Fortunately, I was able to safely land the aircraft by moving the phone but is extremely hard to do with one hand. Am I the only one having issues with landing the Airbus A350-1000 with a broken autopilot?
Operating system:

What app version are you on?

Both the 26.3 and the 26.4 open beta

Is the plane not calibrated before landing?

I calibrated it the second time to see if any difference would happen and it did the same thing :face_exhaling:
