I have just downloaded a pocket query and transferred to my GPS.
The icons have changed totally for all caches types. They are now virtually indistinguishable in the list view and especially so on the maps on the GPS.
I don't think that thought has been given to visually impaired users in this change, as the icon within the circle cannot be differentiated. I am one such affected user.
The old distinct cache types on the map were instantly identifiable.
From us it is a plea of please change the symbols back.
