Signia Pure 312 AX Feedback Entrainment

Hi,

Im wondering if anyone else using Signia Pure 312 AX is having issues with weird sound artifacts when running the feedback cancellation on turbo(max). Often called feedback entrainment. I get loads of weird noises when trying to run them in this mode so I have to run them in normal feedback cancellation which results in feedback when I lay my head down, someone hugs me and so on. Did not have this issue with my old Signia hearing aids. Extremely annoying.
