No Button auto-lock with FW 15.16

Yes what happened to Auto Lock? 

I believe we are talking about auto lock after a timeout here. Not the "Touch lock" that locks the screen and brings this unlock drag up. This method is in practice unusable, better hold down the start until lock/unlock.

- Touch lock does not lock the buttons (by the way).

- The auto lock (by timeout) is implemented in many units like 965 end 955... I have never seen it on the 970 but it should be there.

No. I had it before the last update 

Also see previous discussion. Garmin claims there is no auto lock! But the "Touch lock"...  Very different mechanism I would say.
The auto lock funktion is not documented in the manual. I have not had it before but some says they have. Confusing.
