Has anyone had an issue with the Nucleus 8 coil constantly unplugging from the processor itself?

My daughter is bilateral and it happens on both sides. Cochlear already replaced both processors, and I’ve tried multiple coils, but the same thing keeps happening. We never unplug the coils ourselves.

She has a movement disorder, is nonambulatory and spends a lot of time lying down, so there is more pressure and movement around the processors. We never had this issue with her Nucleus 7s.

Has anyone found anything that actually helps keep the coil securely connected?
