Multiple animations simultaneously on a single object in Manim

I have a Square, and I want to move and scale it at the same time:

sq = Square()
self.add(sq)
self.play(ApplyMethod(sq.scale, 0.5), ApplyMethod(sq.move_to, UP*3))

However, the first animation is skipped and only the last one works.

Is there a simpler solution than using Transform?

There are 3 ways:

class MultipleMethods1(Scene):
    def construct(self):
        sq = Square()
        self.add(sq)
        self.play(
            sq.scale, 0.5,
            sq.move_to, UP*3,
            run_time=5
        )
        self.wait()

class MultipleMethods2(Scene):
    def construct(self):
        sq = Square()
        cr = Circle()
        VGroup(sq,cr).arrange(RIGHT)
        self.add(sq)
        def apply_function(mob):
            mob.scale(0.5)
            mob.shift(UP*3)
            return mob

        self.play(
            ApplyFunction(apply_function,sq),
            ApplyFunction(apply_function,cr),
            run_time=5
        )
        self.wait()

class MultipleMethods3(Scene):
    def construct(self):
        sq = Square()
        self.add(sq)
        sq.generate_target()
        sq.target.scale(0.5)
        sq.target.move_to(UP*3)

        self.play(
            MoveToTarget(sq),
            run_time=5
        )
        self.wait()
