Yup, same here... the minute I get airborne, the FPS drops to almost zero with a terrible stutter.... However, I've got no issues with the A350. I've decided not to fly the A220 until something is done...
I concur. It also happens to me. I've also noticed that after touch down, it tends to lean to either the left or the right mains, causing me to adjust with aileron input.
It happens no matter the airport or weather conditions.
