Please add "Lock" on MX Master3S.
this drives me crazy a hundred times everyday. I feel like I upgraded my MX Master 3 to 3S for absolutely nothing. this could be a downgrade for real. I myself am in SW industry and this cannot be a hard job. so please add "Lock" on MX Master 3S. I'll leave one feed back weekday.
(it's still happening on 1.26.5989)
