The app keeps crashing now

I recently got the iPhone X and tried using this app but it keeps saying “unable to load content. Please check your network and try again.” I tried it without my WiFi and with my WiFi and nothing’s working. I can’t get any songs or see my previous recordings. Is this app not ready for the iPhone X?
