SVG在PC浏览器描边动画正常，在手机浏览器没动画.?

Question

其中文字是SVG图像，通过设置stroke-array和stroke-offset达到描边的动画效果，但是只能在PC浏览器看到。用手机浏览器可以尝试打开，看到的只是静态的svg图像。
问题1：原因是什么？是手机端浏览器暂时不支持svg吗？
问题2：如何解决？

主要代码：
css3

<style>
     @keyframes dash {
      from {
        stroke-dashoffset: 2000;
        opacity: 1;
      }
      to {
        stroke-dashoffset: 0;
      }
    }
      #svg-logo{
           position: absolute;
           left: 50%;
           margin-left: -150px;
         stroke-dasharray: 2000;
         animation:dash 6s forwards linear;
    </style>
