This happens when you tap on the group volume slider. Instead, tap on the group edit icon (to the left of the Play button), that popup will stay up.

Appreciate the rapid response - that does work  .  I am still curious why that one menu defaults to a 3 second dwell to close ?  I’m certain there is logic behind it - but I can’t determine why the developers wanted that menu to close so quickly ?  

I truly love this product -  I do feel there can be a disconnect between the user experience and the desires of a code developer …  that’s only why I inquire

I found it even less intuitive when you tap the group slider and in the pop up, the group volume slider moves down the screen and expands wider, especially on my tablet.

Initially playing chase the volume slider often caused it to close on me with the default timer until I realised ignore what the graphic is doing and just slide the volume control that used to be under my finger. 

Maybe less of an issue on a smaller phone screen, but it seemed like someone switched on the responsive UI switch and considered it done without actually using larger screen sizes
