Abstract

Description

FIG. 1 is a front view of the first image in a sequence of a display screen or portion thereof with transitional graphical user interface, showing our new design;

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1 to 3. The process or period in which one image transitions to another forms no part of the claimed design.

The outer perimeters illustrated by broken lines in FIGS. 1-3 depict a display screen or portion thereof and forms no part of the claimed design. The remaining broken lines depict portions of the graphical user interface that form no part of the claimed design. The contrast shown in grayscale in the claimed portion of FIGS. 1-3 represents a contrast of appearance.
