I'm using an on/off global variable with an auto off formula set to: "$si(screen)!=1$". It's purpose is to reset visiability of certain groups when leaving screen 1. Unfortunately it doesn't appear to turn off when leaving screen 1. I've tested the function itself with a text module to make sure it can detect which screen it is on.
Currently using v3.19b623413 RC4 on an LG G5 running Android 6.0.1
