If you change "Display Size" setting of Android under display settings, total 7 icons (Horizontally) can be placed and 6 normal app shortcuts. Earlier in Android Oreo, it was 6 vs 6, i.e. 6 normal icons and 6 home screen icons.
This is really annoying, as it doesn't look good and smaller icons are difficult to identify. Please help as I always have display size as small.
