I've "A" object with two fields: a lookup field (object B) and a formula field (field status of object b) and a "B" object with lookup field to "A" object. In lightning experience I open record "A" and I go to object B throught lookup field. I modify status of the B object and click to lookup field to return in "A" object. In "A" object I see the old value on formula field. If I refresh page I see the new value. Why the formula field doesn't refresh automatically? In Salesforce classic it work perfectly.
