Urgent : Appointment Slot availability issue with the latest update

Hey there,

After updating the Appointment + to the latest version(2.4.2), we have started getting weird use case and hoping that you guys can help us quickly as this is customer impacting issue.

In appointment for the team member, we have some slots already been booked but they can be seen as it's available on the front end. As soon as we try to fill that slot again, at the end we are getting the error dialog, saying the slot is not available.

we can see the slot booked in the admin panel. It's not happening on the previous version, so that is confirm that it's happening in the new one.

Can you guys please help us out quickly.

Thanks
- Keyur
