Microsoft bookings event content changed

Hello,

I have a problem with Bookings event message. It changed randomly without anyone making changes.

Previously (around 1 week ago) for every submission an event was created. And its content was like this:

***

Vidinės pastabos
-----------------------
This is where you can add notes about this service that only you and your staff see.

***

And now it is like this:

Customer Info
--------------------
Name: Name surname
Phone Number: 0370*******
Time Zone: FLE Standard Time

Booking Info
--------------------
Service name:
Location: { "name": "location of the event" }

Custom Fields
----------------------

Buffer time:
--------------------
Before: 0min(10:10 AM Wed, 30 Aug 2023).
Time with customer: 10:10 AM Wed, 30 Aug 2023–10:15 AM Wed, 30 Aug 2023
After: 0min(10:15 AM Wed, 30 Aug 2023)
Time zone:FLE Standard Time

Does anyone know what could have caused it? Most of our Power Automate scripts became invalid because of the format change.

Thanks in advance!
