Reminder emails sending with incorrect times

Hi everyone,

My work team are using the Bookings app to manage training session bookings and registrations and we have reminder emails set up to auto send 1 day before the scheduled session.

We have recently been notified that some of our reminder emails are going out with the incorrect times and stating UTC Coordinated Universal Time.

Our region and time zone settings are correct (UTC+10 Brisbane), and we have ticked Always show time slots in business time zone, however this shouldn't be an issue as all of our current attendees are located within the same time zone.

The initial booking information and confirmation email show the correct times, and majority of the reminder emails are correct, it's just some of them that change the time. It's not always the same session type either, or for everyone who has registered, it's very sporadic.

We have searched thoroughly through the Bookings system and are unable to find a resolution.

Our attendees have confirmed their time settings in Teams and 365 are correct.

Any ideas of what is causing this or how to fix it?

Thanks,

Cara
