Hi!  I hope someone can clarify - Campaign Influence came up in our Lightning Readiness report "users can't see Campaign Influence related list in Lightning, move to Customizable Campaign Influence".  Long term, we plan to do that, and I have been researching... but meanwhile I noticed that our Primary Campaign Influence dropdown IS visible on our Opportunity details in Lightning!  Is this warning referring only to the Campaign Influence Related List (only truly a problem if there is more than one related Campaign)?
