Moving to official OP11 from the OB2 release - it is more stable and quicker.
The stupid 24hour only clock issue still exists with anything except the default clock; ambient clock still reverts to default clock momentarily on unlock; but so far I haven't spotted any of the other annoying bugs from OB2.
Keyboard rendering with swipe navigation enabled is much improved!
this is all in your head. the speed is virtually identical. I'm staying on OB2 for more cutting edge goodies.
