This is an accepted solution.
There is JS conflict. Check in console of chrome you will find this error.
theme.js?v=8903157658550589297:6070 Uncaught TypeError: Cannot read property 'addressNoResults' of undefined
Once you fix this it will start working again. To fix it you have to manually check the compatibility of custom code you added in theme recently.
Thanks for post
can you please check original theme and custom theme js file or do you have add any app so try disable.
