Timed sound effects on mobile?

So basically when I use something like <<timed 2s>><<audio "bgm_song1" loop play>><</timed>>\, it works fine on my laptop browser but when I run the html on my android tablet or phone none of the timed sound effects work. Other timed elements work and sound effects that occur on passage loads or <<click>>s work. I was just wondering if I'm doing something wrong on my part or if there's a way around it or if it's just a limitation of twine on mobile devices.

Thanks
