"think" doesn't mean "know" ;-) Don't missunderstand me but I'd prefer to hear an official and firm commitment.
Try doing a reset and starting over with your Autotune? I asked a similar question about couple weeks back: Start at 18:35.
FWIW, I'm a new user (just received the Movi this week) and I too noticed the droop, as well as not coming back to center once a few pans are executed. I've set the Window and locks to different parameters, reset, and used autotune. After a while, same results of droop and off center from original balance and start. As Andy mentioned early in this thread, he made note of it to FF dev team for a, hopefully very soon, update release.
