Assume we have ObjectA__c with Field1__c and ObjectB__c with formula field Field2__c which is formula to ObjectA__r.Field1__c.
I expected change of record field Field1__c of ObjectA__c would cause trigger on ObjectB__c to fire with changed Field2__c field, but this doesn't happen.
Can anyone explain why? Alternatively, can anyone share link to docs where is behavior is explained?
