From the source cited by Longtimer: "It (Airbus) has not elaborated on the situation beyond stating that "excessive" pitch could occur under certain conditions and "during specific manoeuvres". Isn't that sort of pitch up problem why MCAS was developed by Boeing? What's going on here? Does the A321neo also have a problem with pitch instability?
This is the first I've heard of a possible pitch stability problem with the A-321neo. Let's hope that no lives are lost before the problem can be rectified.
