Primary Contact on opportunties

Dear all,just a question regarding primary contacs, maybe one of you has a solution already.

In Classic if I click on the New button in contact roles under opportunities I get a list of all my related contacts from the account.

In Lightning I goto Contact roles and can manage my contact roles but I do not see the list of related contacts. This is very disturbing especially it was quite comfortable in Classic.

Does anyone have a solution maybe?

Thanks and best regards

Martin
