Two issues with engine stop-start

Has anyone else had either of these issues with their auto stop-start?

1. Stalling after restarting when moving on at a traffic light - engine switches off when the traffic light is red, when the traffic light turns green, accelerator is pressed and engine comes back on but as I go to move on it turns off agin.

2. Slowing down to give way, I don't come to a complete stop but the car shakes/vibrates as though it wants to shut down.

I feel it needs to be recalibrated so that the auto stop doesn't activate until I've come to a complete stop for a few seconds, whereas at the moment it stops the engine so quickly and sometimes even when I haven't completely stopped. I'd be interested in everyone else's experiences.

I noticed the "early" stops in the beginning. Off course this also resulted in some noticeable vibrates when I accelerated again when engine was just stopping.
That however, went away after a few weeks. Think the car needs to learn your behavior or I learned how to adapt to the functionality.

Stalling when driving away after starting hasn't happened to me.

Turn it off after you start the car or put it in sport. You can get it coded to remember the last setting in comfort.

Experienced neither. Seems it's getting not the proper amount of fuel.
