Didn't know that about the settings, but I did confirm it. I'll report it to the devs, thanks.You all probably know this but the pie functionality won't retain its anchor points after the screen goes to sleep. So if it started on the left and you move it anywhere else, once you lock and unlock the device its back on the left. Clicking the settings option fails to open anything. Locks screen
However, anchoring it to the bottom works for me and survives locking and unlocking. Can you go through the steps you used and I'll try to reproduce it here.
