Regarding your question, for trees with less than or equal to 5000 people, you can see all relationships.
For trees with over 5000 people and less than 17,000 individuals it is limited:
* for direct ancestors/descendants you can see relationships of up to 20 degrees
* for non-direct relatives, you can only see the relationships for people that are 2 steps away.
This is a known behaviour of the on-line display tree and we currently do not have plans to change this in the near future.
For further enquiries and more direct contact with MyHeritage Support, you are more than welcome to contact us directly on firstname.lastname@example.org.
