While searching a solution for “undefined” error on smartphone, I noticed that there was a post, but no solution.
I am having a same problem.
From Desktop, it works fine.
From Smartphone (Samsung Galaxy), using Chrome, once clicking, the screen says “Underfined” and the no user information/data is the appt. list.
How to solve this? This is a kind of urgent since most of customers are using smartphone.
can you please share the link to that page so I can test it. Can you please also test this on your mobile for same error? https://easy-appointments.net/responsive-single-column-layout/
