Smule has the nerve to charge a membership fee and this app is a glitchfest 24-7. Every single instance without fail in "live room" when a host invites me to duet in a live session the app completely freezes up when I attempt to pick up the mic. The only solution is to restart app and painfully search for live session again to join the host and by that time they have moved on to someone else in the waitlist. Absolutely despicable. The android app also lacks many features that iOS users enjoy.
