"unfortunately, musical.ly has stopped" - how to fix?

A

AC Question

Both my daughter's and my own Musical.ly apps on our nexus android phones gives us this message. Both happened this week within 24 hours of each other. When we try to open the app, it either doesn't open or it gives us this message: "unfortunately, musical.ly has stopped"

Anyone know what's going on?

Is there a way to fix it?

If we uninstall, will we use the private musical.ly that we made?
