When you open a contact or account record and go to a list view of related records (for example opportunity), you can see a list of open opportunities. If you open up an opportunity and make changes then exit, it should take you back to the list of opportunities.

Instead it takes you back to the main contact or account record. In CRM 2013, it worked by taking you back to the list view. D365 (8.2) takes you back to the contact or account record.

Suggestion: Revert back to functionality of CRM 2013.
