Mine still does, three finger swipe up, choose second app, split screen.

Give that a shot and see if it works?

I use all gensture navigation, so it might be different if you use the three buttons.

If you are, I am. Remember the hive?

Edit : well, I guess the memory issues are coming too. I remembered the hive was enshrined in erowid after it shut.

Its weird as shit too. All kinds of kid maintenance people get really weirded out when you come in with informed kids who know exactly what the procedure is, what goes on, and has their own questions about it appropriate for a 5 year old.

They expect you lie to your children, about anything that might be unpleasant and just let it be a traumatic surprise ( this is what my parents did )
