I have a calendar on my jotform where I disabled booking on Wednesdays, and somehow, someone was still able to book. Can you please look into this?

Here is how it's set up in the back end...

Here is a shot of the registration confirmation I received.

Hello,

Thank you for reaching out.

I haven't been able to reproduce the issue on my end and I do confirm that I couldn't book an appointment for that date.

It was more than likely a glitch.

We apologize for the inconvenience this may have caused.

Thanks for getting back to me so quickly. The user sent me a copy of their booking that had a timestamp from Asia, which translates to the time she booked in EST. How would this have happened?

Hello,

I have cloned your form, and I can't seem to replicate the issue on my end, and my location is in Asia. I can also see that the Appointment Field is set to "America/Toronto Time" as the Default Time Zone, and I have checked as well the submissions on your form, and they are showing the same time zones for the Selected Date and Time.

May we ask for the submission ID of the screenshot that you have provided above? Also, is your form embedded on a website? If it is, please provide us with the URL where the form is embedded to investigate it further.

Thank you. Looking forward to your response.

I think what happened was that the registrant accidentally changed her time zone when she was entering it. So the Thursday @ 6AM (Asia time) appointment she thought she was booking was actually Wednesday @ 7PM (Toronto time). Maybe she wouldn't have seen it blocked because I blocked Wednesdays, and she was booking what appeared to be Thursday.

The form is not embedded on a website.

This is the submission ID: 4833485990117231138

I believe that is the cause of this issue. The appointment was booked based on the user's timezone which she changed. I did check your form and it seems you have injected custom CSS code to hide the timezone option for users.

Please monitor your submissions and get back to us if you see this issue again, and we will take a look.

We will wait for your response.
