We claim the ornamental design for a display screen or portion thereof with animated graphical user interface, as shown and described.
FIG. 1 is the first image in a sequence for a display screen or portion thereof with animated graphical user interface showing our new design;
FIG. 2 is the second image thereof;
FIG. 3 is the third image thereof; and,
FIG. 4 is the fourth image thereof.
The outer perimeter broken lines in the drawings represent a display screen or portion thereof and form no part of the claimed design. The remaining broken lines in the drawings illustrate portions of the animated graphical user interface that form no part of the claimed design.
The appearance of the animated images sequentially transition between the images shown in FIGS. 1-4. The process or period in which one image transitions to another image forms no part of the claimed design.
