FIG. 3 is the third image thereof;

FIG. 4 is the fourth image thereof;

FIG. 5 is a fifth image thereof;

FIG. 6 is a sixth image thereof; and,

FIG. 7 is a seventh image thereof.

The two closely spaced broken lines at the perimeter in the figures illustrate a display screen or portion thereof and form no part of the claimed design. The remainder of the broken lines illustrate portions of the animated graphical user interface and form no part of the claimed design.
