Freesounds.org Sounds on Smart Devices?

I am an educator using Soundtrap with my students, and I had been looking forward to using the Sounds from freesounds.org with my students who observe Ramadan this month, as many of them are not able to listen to or make music during fasting hours (also school hours). We have discovered that these non-musical sounds are only accessible on laptop/computer devices and NOT on iPads, iPhones, and other smart devices. Is there a workaround for this or a way other than this forum to formally request access expansion for this tool? Thank you!
