Autolock feature

Hi guys,

As I usually say, you helped me many times, so far.

I have a rather technical question to understand the “lock or auto-lock” function because we are trying to test “extreme scenarios”, when 2 clients try to book the same day, same service, same time slot, and figure out “who wins” if it makes sense. I don’t know if it is related to the “auto-lock feature”. I made a screencast video as well.

So, the scenario is the following:

2 customers are booking the same time, and both are trying to book the same service, let’s say, Monday at 9:00 AM, May 6, in our video example.

As you can see, both customers are choosing the same service for the same timeslot, but

• “Customer Right Window” is a bit faster and – this is my question –> locks(?) or just “tries” to book at 9 AM, and HAS NOT sent/finalized the booking, yet, but is only on the name/email/phone fields window.
• “Customer Left Window” is slower, so they are trying to book the same 9 AM, and they could, as you can see the 9 AM time slot is available for them, too (which is my question if that can be prevented)

This is what I am trying to understand, so

• “When” will the 9:00 AM slot be “locked”? only after when the booking is sent?
• In my mind it should be right after the faster one (Right window) picks the time 9:00 AM and clicks the “next” (“tovább” in Hungarian) button, so as soon as the quicker customer clicks “next” after the 9:00 AM time slot selected, it should be locked (in my understanding), so the other/slower customer no more could/should be able to select/book that 9:00 AM appointment.
• But in our video example, both customers (booking at the same time) CAN book the same 9 AM time slot, which is strange for me because this way the “auto-lock” feature does not make sense to me, please explain what this feature is then.
• If I finish such a booking, the system returns an error message to the slower (Left window) customer that the booking was not made, which is fine, but – again – I thought that the auto-lock feature would PREVENT the slower customer from even selecting the already selected (9:00 AM) time slot by the quicker customer after they clicked “next”, I thought this “next” click would “register the booking” as a kind of “temporary lock/booking”, so that time slot cannot be picked if someone is trying to make the same booking.

settings: https://ibb.co/ZzG6RCW (the reason why we perform auto-lock for the categories is that the salon has 2 devices that can work and, therefore be booked at the same time, but in our case, the 2 customers picked the same device (service) for a treatment at the same time.)

I hope it makes sense what I’m trying to ask ??
Thank you in advance for your help!
Kind regards, Gabe
