The new update has a setting for 3D to only work on small maps.
Sadly Fizzer overwritten the previous settings with this new one, so everyone's 3D settings went back to "on for small maps", so if you play mostly big maps, you might want to change that setting to "on" to have it work for all maps.
The reason those maps still work in 3D on your phone, is because your phone probably didnt update yet.
