    Hi!


    The Appointment Widget is working just fine in my form, however, there are instances that there are two "bookings" in one slot. 

    Is it possible that two people can click on the same time-slot at the same time that can cause double booking? if yes, how doe we avoid it?  Is there a way that the Appointment Widget be updated in realtime to cross-out time slots that no longer available?

    Thank you for your help.

    Thanks for reporting. I was able to reproduce this problem.

    It seems somehow possible when you do it at the same time. Example, both users pick the same slot and submits the form almost at the same time (with at least a half a second gap).

    However, it is not possible when both the user picks the same slot and the first user able to submit it first. This blocks the second user's selection.

    I will forward this to our developers so hopefully, they'll be able to find a solution to prevent double appointments when both users submit the form at the same time although, from my knowledge, an occurrence like this is usually the ones hard to resolve.

    We will let you know once we have a solution.

    The issue has been escalated to our developers. We will contact you again on this thread once we have an update.

    For the meantime, please try adding a Captcha widget to your form to avoid duplicate submission or at least a delay when two user tries submitting at the same time.
