Relationship not showing up in Related tab
I'm setting up Insightly for a client who works in the property sector. Each Contact can own multiple Properties.
We've created a Custom Object named "Property" and setup some sample records.
Within the Property Custom Object, we've created a field named "Property Owner", which is a Lookup Relationship field of type Contact. We've also setup the Field Label, Field Name and Related List Name as per the instructions in the article: https://support.insight.ly/hc/en-us/articles/360007816233-How-to-use-lookup-relationship-fields-with-custom-objects.
We've setup the Property's "Property Owner" field to be an existing Contact in Insightly.
When we click the Related tab of that Property, we still see the message "This object is not linked to any other objects. Add a lookup relationship field to connect this object to another object."
We've also tried the other way around, i.e. creating a Lookup Relationship field in Contacts of type Property. We've given the Related List Name field a value, however we don't see any way to list a related Property in the Related tab - it only shows other Lookup Relationship fields (Organizations etc. and a Custom Field named Client Manager of type Contact).
Are we missing something in the setup of the Lookup Relationship field? We've tried a lot of variations, including naming the field to "PropertyOwnedByContact" so it's got no spaces in the name.
