How to create a view that shows a Managing User all content of their members?
First of all create a view of all content.

Next, add a relationship to the author of the content. Call the relationship author. Check 'require this relationship'.

Next, add a contextual filter on the entity reference field to the manager, using the author relationship. Under 'When the filter is not available' select 'Provide a default value', and choose 'User ID from logged in user'.

Let me know if it works for you.

And here is an export of my view - you should be able to import this and it will just work:

$view = new view();
