Jio music is good at its performance according to is design but this is a slow responding app that I have ever seen and also we can use this only if we set jio as main network this is a drawback of this app .startup of the app is very slow if we are a jio user it should be like using our jio id password we should be able to use jio apps with any network and any preference to any simif this is agreed and developed as a bug it would be cool to use many of the jio apps
