We can’t find the Reservations related list in the Contact Lightning Record Page.

You added Reservations, but it should be added to the Related tab.

it was my fault, I realized I hadn't renamed "external reservations" to "reservations"

the link above helped me fix it. There are two steps that are marked as optional depending on your org configuration and I needed to do the first of the two to fix the display name.

i have found my misstake.

In the step before where i have set up the "Data Cloud Related List" i have changed the name from the auto generated Child Relationship Name from "ExternalReservation" to only "Reservation" by removing the "External" to save time.

But the Trail expects the name to be "Reservations" with an "s" on the end.

The Label was correct "Reservations" so you dont see that Child Relationship Name later in the ui and dont see this error.

had the same problem. For me it was due to the related list enrichment wizard that didn't show the Child Relationship Name.

Go to Object manager -> contact -> data cloud related list

Click on "Reservations" -> edit details on the upper right

Check that in both fields you have the "Reservations" value
